Sphere Packing
Sphere Packing
2014
"Sphere Packing" is a series of 3D-printed pieces designed to concentrate the entire musical production of a composer in a single dense multi-channel device. The size of each sphere is directly proportional to how prolific the composer was, for example the sphere for Johann Sebastian Bach has 48 cm diameter and holds 1100 loudspeakers playing simultaneously Bach's 1100 different compositions, while the sphere for Hildegaard Von Bingen only has 11 cm diameter and 69 loudspeakers. The project presents at a glance the comparative production volume of many composers. As people are a couple metres away from a sphere they hear a quiet murmur of sounds, but as they approach and put their ear up close to individual speakers they can hone in on specific compositions.

Method Random
Method Random
2014
“Method Random” is a series of chromogenic prints that have been generated by computational methods that attempt to create randomness. Random number generators (RNG) are essential algorithms for a large number of applications from encryption and security to simulation, jury selection, double-blind trials, statistical sampling, game theory and many others. While the sum of all colours picked by different RNG algorithms generates a neutral gray, patterns can be discerned when massive number of pixels can be seen simultaneously. These prints show how human perception of organization can often spot the fundamental difficulty for computers to appear unpredictable. View Details.
Vicious Circular Breathing
Vicious Circular Breathing
2013
Vicious Circular Breathing is a hermetically-sealed apparatus that invites the public to breathe the air that was previously breathed by participants before them. The installation consists of a glass room with double sliding doors, two emergency exits, carbon dioxide and oxygen sensors, a set of motorized bellows, an electromagnetic valve system, and 61 brown paper bags hanging from respiration tubes. In the piece, visitors’ breath is kept circulating and made visible by automatically inflating and deflating the brown paper bags around 10,000 times a day, the normal respiratory frequency for an adult at rest. The piece includes warnings for asphyxiation, contagion and panic, and produces a faint mechanical sound, a quiet whir from the air flow and louder crackles from the crumpling bags. View Details.
Voice Tunnel
Voice Tunnel
Relational Architecture 21, 2013
An installation designed to transform the Park Avenue Tunnel in New York City with 300 theatrical spotlights that produce glimmering arches of light along the tunnel’s walls and ceiling. Participants control the intensity of each light by speaking into an intercom at the tunnel’s center which records their voice and loops it. Louder speech increases the lights’ brightness proportionally, creating a Morse-like code of flashes throughout the tunnel. The individual voices can be heard as pedestrians walk through the tunnel, on 150 loudspeakers, one beside each light arch and synchronized with it. At any given time, the tunnel is illuminated by the voices of the past 75 participants: as new participants speak into the intercom, older recordings get pushed away by one position down the array of light fixtures until they leave the tunnel, so that the content of the piece is changing constantly.

Performance Review
Performance Review
2013
Performance Review is a photographic project comprised of thousands of fingerprints captured by high magnification digital surveillance equipment. While the distinctive patterns found in friction ridges of the human finger allow for the identification of an individual, in these images those singularities are subsumed to create an ambiguous image, representing the generalized use of biometry itself. Named after 15 banks, the c-prints in this series are unique, each consisting of fingerprints from 750 different people. View Details.
Airborne
Airborne
Relational Architecture 20, 2013
“Airborne” was an interactive installation commissioned by the Chrysler Museum of Art to transform Norfolk’s public space into a poetic shadow play. Participants blocked the light of two projectors casting their shadows on a 900 sqm wall, and these were tracked by computerized surveillance systems. Out of the shadows emanated bellowing smoke which was mapped onto the wall and accumulated in it. Readable within the smoke were clouds of text, themselves turbulent, from salient poetic texts on light and shadow. View Details.

Tape Recorders
Subsculpture 14, 2011
Rows of motorised measuring tapes record the amount of time that visitors stay in the installation. As a computerised tracking system detects the presence of a person, the closest measuring tape starts to project upwards. When the tape reaches around 3 meters high it crashes and recoils back. Each hour, the system prints the total number of minutes spent by the sum of all visitors. View Details.
Voice Array
Voice Array
Subsculpture 13, 2011
As a participant speaks into an intercom, his or her voice is automatically translated into flashes of light and then the unique blinking pattern is stored as a loop in the first light of the array. Each new recording pushes all previous recordings one position down and gradually one can hear the cumulative sound of the 288 previous recordings. The voice that was pushed out of the array can then be heard by itself. View Details.
Nave Solar
Nave Solar
2011
Nave Solar is an interactive installation featuring a fake Sun that is activated by the pendular motion of the public as they hang from a rope and swing along the nave of a 16th Century catholic inquisition church. Using tracking systems, the installation detects the motion of participants and generates smoke that accumulates on the ceiling of the apse as well as activates the Sun's flares, surface turbulence and sun spots.

Articulated Intersect
Articulated Intersect
Relational Architecture 18, 2011
“Articulated Intersect” is a large-scale installation that produces an interactive canopy of light that can be modified by the public using six large lever-controllers that protrude from the ground. As a participant points one of these levers three powerful robotic searchlights automatically intersect in the sky to create an apex at that location. The participant may direct the apex anywhere over the city in real-time, creating an animated tetrahedron inspired by the work of Richard Buckminster Fuller. View Details.
Flatsun
Flatsun
2011
A circular display that simulates the turbulence at the surface of the Sun using mathematical equations. The piece reacts to the presence of the public by varying the speed and type of animation displayed. If no one is in front of the piece the turbulence slows down and eventually turns off. As the built-in camera detects people, more solar flares are generated and the fake Sun shows more perturbation and activity. At 140 cm diameter, Flatsun is exactly a billion times smaller than the real Sun. View Details.

Sandbox
Sandbox
Relational Architecture 17, 2010
Sandbox is a large-scale interactive installation created originally for Glow Santa Monica. The piece consists of two small sandboxes where one can see tiny projections of people who are at the beach. As participants reach out to touch these small ghosts, a camera detects their hands and relays them live to two of the world's brightest projectors, which hang from a boom lift and which project the hands over 8,000 square feet of beach. In this way people share three scales: the tiny sandbox images, the real human scale and the monstrous scale of special effects. View Details.
Please Empty Your Pockets
Please Empty Your Pockets
Subsculpture 12, 2010
Please Empty your Pockets is an installation that consists of a conveyor belt with a scanner that records and accumulates everything that passes under it. The public may place any small object on the conveyor belt: once it passes under the scanner, the object reappears on the other side beside projected objects from the memory of the installation. As a real item is removed from the conveyor belt, it leaves behind a projected image of itself, which is then used to accompany future objects. The piece remembers up to 600,000 objects which are displayed beside new ones that are added to the installation. View Details.
Autopoiesis
Autopoiesis

Solar Equation
Solar Equation
Relational Architecture 16, 2010
"Solar Equation" is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing. Commissioned by the Light in Winter Festival in Melbourne, the piece features the world’s largest spherical balloon, custom-manufactured for the project, which is tethered over Federation Square and animated using five projectors. The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun. This produces a constantly changing display that never repeats itself, giving viewers a glimpse of the majestic phenomena that are observable at the solar surface and that only relatively recent advances in astronomy have discovered. Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations. View Details.

It is comprised of photomontages and a video with 1,000 words or expressions commonly used to promote globalised cities to potential investors, such as "open", "modern", "clean", "multicultural" and "cosmopolitan", for example. To make these images, a powerful projector (110,000 ANSI lumens of intensity for images of up to 70 x 70 metres) was placed on a 12-ton truck with a generator. View Details.
Two Origins
Two Origins
Relational Architecture 7, 2002
In this intervention the emblematic Place du Capitole in Toulouse was transformed by a projection of The Book of Two Origins, a 13th-century heretical manuscript compiling the theological beliefs of the dualist cathars. Once a vibrant community in several regions of Europe, the believers in the two origins of the Universe were virtually annihilated by the brutal crusades that gave birth to the Inquisition and France's expansion. The texts are illegible since they are projected overlapping each other on the same façade from two distant projectors; only when passers-by block one text with their bodies is it possible to read the other text inside their shadow.

Solar Equation
Solar Equation
Relational Architecture 16, 2010
"Solar Equation" is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing. Commissioned by the Light in Winter Festival in Melbourne, the piece features the world’s largest spherical balloon, custom-manufactured for the project, which is tethered over Federation Square and animated using five projectors. The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun. This produces a constantly changing display that never repeats itself, giving viewers a glimpse of the majestic phenomena that are observable at the solar surface and that only relatively recent advances in astronomy have discovered. Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations. View Details.
Sphere Packing
Sphere Packing
2014
"Sphere Packing" is a series of 3D-printed pieces designed to concentrate the entire musical production of a composer in a single dense multi-channel device. The size of each sphere is directly proportional to how prolific the composer was, for example the sphere for Johann Sebastian Bach has 48 cm diameter and holds 1100 loudspeakers playing simultaneously Bach's 1100 different compositions, while the sphere for Hildegaard Von Bingen only has 11 cm diameter and 69 loudspeakers. The project presents at a glance the comparative production volume of many composers. As people are a couple metres away from a sphere they hear a quiet murmur of sounds, but as they approach and put their ear up close to individual speakers they can hone in on specific compositions.

The Year's Midnight
2011
"The Year's Midnight" is an interactive installation that shows the viewers' image on screen, unprocessed, except for plumes of white or black smoke that emanate from their eye sockets until the whole display is filled with a dense smog. Live and recorded eyeballs extracted from the video accumulate on the bottom of the display, similar to traditional representations of St. Lucy. The project's name is the beginning of John Donne's "A Nocturnal Upon St. Lucy's Day, Being the Shortest Day", a mournful poem which inspires this work. View Details.
There Is No Business Like No Business
There Is No Business Like No Business
2009
A blinking neon sign, designed during the recession as a cruel beacon of optimism. The blinking speed is directly proportional to the trading volume of any commodity index chosen by the collector or curator, say NASDAQ or Apple or FTSE100. In a slow day, or when the market is closed, the lines of illuminated text will only switch every 8 seconds, while on the busiest trading day they may blink every 2 seconds. View Details.
Third Person
Third Person
Shadow Box 2, 2006
"Third Person" is the second piece of the ShadowBox series of interactive displays with a built-in computerized tracking system. This piece shows the viewer's shadow revealing hundreds of tiny words that are in fact all the verbs of the dictionary conjugated in the third person. The portrait of the viewer is drawn in real time by active words, which appear automatically to fill his or her silhouette. The collector may choose to display the words in English, Spanish or French, or a combination of the three languages. View Details.
Two Origins
Two Origins
Relational Architecture 7, 2002
In this intervention the emblematic Place du Capitole in Toulouse was transformed by a projection of The Book of Two Origins, a 13th-century heretical manuscript compiling the theological beliefs of the dualist cathars. Once a vibrant community in several regions of Europe, the believers in the two origins of the Universe were virtually annihilated by the brutal crusades that gave birth to the Inquisition and France's expansion. The texts are illegible since they are projected overlapping each other on the same façade from two distant projectors; only when passers-by block one text with their bodies is it possible to read the other text inside their shadow.

Under Scan
Relational Architecture 11, 2005
"Under Scan" is a public art installation based on self-representation. Thousands of "video-portraits" taken in Derby, Leicester, Lincoln, Northampton and Nottingham are projected onto the ground; at first, the portraits are not visible because the space is flooded by white light coming from a high-powered projector. As people walk around the area, their shadows are cast on the ground, revealing the video-portraits in short sequences. View Details.
Vectorial Elevation
Vectorial Elevation
Relational Architecture 4, 1999
"Vectorial Elevation" is an interactive art project originally designed to celebrate the arrival of the year 2000 in Mexico City's Zócalo Square. The website www.alzado.net enabled any Internet user to design light sculptures over the city's historic centre, with eighteen searchlights positioned around the square. These searchlights, whose powerful beams could be seen within a 15 kilometers radius, were controlled by an online 3D simulation program and visualised by digital cameras. A personalised webpage was produced for every participant with images of their design and information such as their name, dedication, place of access and comments. View Details.
Vicious Circular Breathing
Vicious Circular Breathing
2013
Vicious Circular Breathing is a hermetically-sealed apparatus that invites the public to breathe the air that was previously breathed by participants before them. The installation consists of a glass room with double sliding doors, two emergency exits, carbon dioxide and oxygen sensors, a set of motorized bellows, an electromagnetic valve system, and 61 brown paper bags hanging from respiration tubes. In the piece, visitors’ breath is kept circulating and made visible by automatically inflating and deflating the brown paper bags around 10,000 times a day, the normal respiratory frequency for an adult at rest. The piece includes warnings for asphyxiation, contagion and panic, and produces a faint mechanical sound, a quiet whir from the air flow and louder crackles from the crumpling bags. View Details.
Voice Array
Voice Array
Subsculpture 13, 2011
As a participant speaks into an intercom, his or her voice is automatically translated into flashes of light and then the unique blinking pattern is stored as a loop in the first light of the array. Each new recording pushes all previous recordings one position down and gradually one can hear the cumulative sound of the 288 previous recordings. The voice that was pushed out of the array can then be heard by itself. View Details.
Voice Tunnel
Voice Tunnel
Relational Architecture 21, 2013
An installation designed to transform the Park Avenue Tunnel in New York City with 300 theatrical spotlights that produce glimmering arches of light along the tunnel’s walls and ceiling. Participants control the intensity of each light by speaking into an intercom at the tunnel’s center which records their voice and loops it. Louder speech increases the lights’ brightness proportionally, creating a Morse-like code of flashes throughout the tunnel. The individual voices can be heard as pedestrians walk through the tunnel, on 150 loudspeakers, one beside each light arch and synchronized with it. At any given time, the tunnel is illuminated by the voices of the past 75 participants: as new participants speak into the intercom, older recordings get pushed away by one position down the array of light fixtures until they leave the tunnel, so that the content of the piece is changing constantly. View Details.
Voz Alta

“Zero Noon” is a digital clock that shows the current time according to eccentric metrics: it uses hundreds of different internet-refreshed statistics. The clock's reference systems are all synchronized so that precisely at noon they all zero and start over. The public may change the statistics by manually scrolling through the list using small push-buttons under the built-in display. The metrics come from government data, Harper’s Magazine, financial institutions, NGOs, academic studies and other trusted sources. View Details.
Levels of Nothingness
Levels of Nothingness
Performers 1, 2009
An installation-performance commissioned for the 50th Anniversary of the Guggenheim Museum, inspired by Kandinsky's opera, "The Yellow Sound" (1912). In "Levels of Nothingness", the human voice is analyzed by computers, automatically controlling a full rig of Rock-and-Roll concert lighting and creating an interactive colour show. For the New York performances, Isabella Rossellini read a libretto co-written by Brian Massumi, which included seminal philosophical texts on skepticism, color and perception, including writings by Kandinsky, Deleuze, Sanches, Simon Baron-Cohen and Alexander Luria. Following the performances, audience members could test the color-generating microphone. View Details.

Solar Equation
Solar Equation
Relational Architecture 16, 2010
"Solar Equation" is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing. Commissioned by the Light in Winter Festival in Melbourne, the piece features the world’s largest spherical balloon, custom-manufactured for the project, which is tethered over Federation Square and animated using five projectors. The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun. This produces a constantly changing display that never repeats itself, giving viewers a glimpse of the majestic phenomena that are observable at the solar surface and that only relatively recent advances in astronomy have discovered. Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations. View Details.
Sandbox

Relational Architecture 17, 2010
Sandbox is a large-scale interactive installation created originally for Glow Santa Monica. The piece consists of two small sandboxes where one can see tiny projections of people who are at the beach. As participants reach out to touch these small ghosts, a camera detects their hands and relays them live to two of the world's brightest projectors, which hang from a boom lift and which project the hands over 8,000 square feet of beach. In this way people share three scales: the tiny sandbox images, the real human scale and the monstrous scale of special effects. View Details.

Performance Review
Performance Review
2013
Performance Review is a photographic project comprised of thousands of fingerprints captured by high magnification digital surveillance equipment. While the distinctive patterns found in friction ridges of the human finger allow for the identification of an individual, in these images those singularities are subsumed to create an ambiguous image, representing the generalized use of biometry itself. Named after 15 banks, the c-prints in this series are unique, each consisting of fingerprints from 750 different people. View Details.
Flatsun
Flatsun
2011
A circular display that simulates the turbulence at the surface of the Sun using mathematical equations. The piece reacts to the presence of the public by varying the speed and type of animation displayed. If no one is in front of the piece the turbulence slows down and eventually turns off. As the built-in camera detects people, more solar flares are generated and the fake Sun shows more perturbation and activity. At 140 cm diameter, Flatsun is exactly a billion times smaller than the real Sun. View Details.

Navier-Stokes
Navier-Stokes
2009
"Navier-Stokes" is a series of computer-controlled lightboxes that show satellite pictures of border regions that have a vector of economic disparity, a history of military conflict or heavy migratory traffic. Instead of using regular white fluorescent light tubes to illuminate the print, the pieces have over one hundred thousand light emitting diodes (LEDs), which can highlight tiny features within the image. The first piece shows the Tijuana-San Diego border with Mexico illuminated red by default while the US is dark. View Details.
Airborne
Airborne
Relational Architecture 20, 2013
“Airborne” was an interactive installation commissioned by the Chrysler Museum of Art to transform Norfolk’s public space into a poetic shadow play. Participants blocked the light of two projectors casting their shadows on a 900 sqm wall, and these were tracked by computerized surveillance systems. Out of the shadows emanated bellowing smoke which was mapped onto the wall and accumulated in it. Readable within the smoke were clouds of text, themselves turbulent, from salient poetic texts on light and shadow. View Details.

The Year's Midnight
2011
"The Year's Midnight" is an interactive installation that shows the viewers' image on screen, unprocessed, except for plumes of white or black smoke that emanate from their eye sockets until the whole display is filled with a dense smog. Live and recorded eyeballs extracted from the video accumulate on the bottom of the display, similar to traditional representations of St. Lucy. The project's name is the beginning of John Donne's "A Nocturnal Upon St. Lucy's Day, Being the Shortest Day", a mournful poem which inspires this work. View Details.
Pulse Index
Pulse Index
2010
"Pulse Index" is an interactive installation that records participants’ fingerprints at the same time as their heart rates. The piece displays data for the last 765 and over participants in a stepped display that creates a horizon line of skin. As new recordings are added, the oldest ones disappear, —a kind of memento mori. To participate, people introduce their finger into a custom-made sensor equipped with a digital microscope and a heart rate sensor; their fingerprint immediately appears on the largest cell of the display, pulsating to their heart beat.

Displaced Emperors
Displaced Emperors
Relational Architecture 2, 1997
"Displaced Emperors" was an installation that used an "architact" interface to transform the Habsburg Castle in Linz, Austria. Wireless 3D sensors calculated where participants pointed to on the façade and a large animated projection of a hand was shown at that location. As people on the street "caressed" the building, they could reveal the interiors of the Habsburg residence in Mexico City, Castillo de Chapultepec. View Details.
Two Origins
Two Origins
Relational Architecture 7, 2002
In this intervention the emblematic Place du Capitole in Toulouse was transformed by a projection of The Book of Two Origins, a 13th-century heretical manuscript compiling the theological beliefs of the dualist cathars. Once a vibrant community in several regions of Europe, the believers in the two origins of the Universe were virtually annihilated by the brutal crusades that gave birth to the Inquisition and France's expansion. The texts are illegible since they are projected overlapping each other on the same façade from two distant projectors; only when passers-by block one text with their bodies is it possible to read the other text inside their shadow.

Method Random
Method Random
2014
“Method Random” is a series of chromogenic prints that have been generated by computational methods that attempt to create randomness. Random number generators (RNG) are essential algorithms for a large number of applications from encryption and security to simulation, jury selection, double-blind trials, statistical sampling, game theory and many others. While the sum of all colours picked by different RNG algorithms generates a neutral gray, patterns can be discerned when massive number of pixels can be seen simultaneously. These prints show how human perception of organization can often spot the fundamental difficulty for computers to appear unpredictable. View Details.

Solar Equation
Solar Equation
Relational Architecture 16, 2010
"Solar Equation" is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing. Commissioned by the Light in Winter Festival in Melbourne, the piece features the world’s largest spherical balloon, custom-manufactured for the project, which is tethered over Federation Square and animated using five projectors. The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun. This produces a constantly changing display that never repeats itself, giving viewers a glimpse of the majestic phenomena that are observable at the solar surface and that only relatively recent advances in astronomy have discovered. Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations. View Details.

Sphere Packing
Sphere Packing
2014
"Sphere Packing" is a series of 3D-printed pieces designed to concentrate the entire musical production of a composer in a single dense multi-channel device. The size of each sphere is directly proportional to how prolific the composer was, for example the sphere for Johann Sebastian Bach has 48 cm diameter and holds 1100 loudspeakers playing simultaneously Bach's 1100 different compositions, while the sphere for Hildegaard Von Bingen only has 11 cm diameter and 69 loudspeakers. The project presents at a glance the comparative production volume of many composers. As people are a couple metres away from a sphere they hear a quiet murmur of sounds, but as they approach and put their ear up close to individual speakers they can hone in on specific compositions.

Voice Tunnel
Voice Tunnel
Relational Architecture 21, 2013
An installation designed to transform the Park Avenue Tunnel in New York City with 300 theatrical spotlights that produce glimmering arches of light along the tunnel’s walls and ceiling. Participants control the intensity of each light by speaking into an intercom at the tunnel’s center which records their voice and loops it. Louder speech increases the lights’ brightness proportionally, creating a Morse-like code of flashes throughout the tunnel. The individual voices can be heard as pedestrians walk through the tunnel, on 150 loudspeakers, one beside each light arch and synchronized with it. At any given time, the tunnel is illuminated by the voices of the past 75 participants: as new participants speak into the intercom, older recordings get pushed away by one position down the array of light fixtures until they leave the tunnel, so that the content of the piece is changing constantly.

“Articulated Intersect” is a large-scale installation that produces an interactive canopy of light that can be modified by the public using six large lever-controllers that protrude from the ground. As a participant points one of these levers three powerful robotic searchlights automatically intersect in the sky to create an apex at that location. The participant may direct the apex anywhere over the city in real-time, creating an animated tetrahedron inspired by the work of Richard Buckminster Fuller. View Details.
Tape Recorders
Tape Recorders
Subsculpture 14, 2011
Rows of motorised measuring tapes record the amount of time that visitors stay in the installation. As a computerised tracking system detects the presence of a person, the closest measuring tape starts to project upwards. When the tape reaches around 3 meters high it crashes and recoils back. Each hour, the system prints the total number of minutes spent by the sum of all visitors. View Details.
Voice Array
Voice Array
Subsculpture 13, 2011
As a participant speaks into an intercom, his or her voice is automatically translated into flashes of light and then the unique blinking pattern is stored as a loop in the first light of the array. Each new recording pushes all previous recordings one position down and gradually one can hear the cumulative sound of the 288 previous recordings. The voice that was pushed out of the array can then be heard by itself. View Details.
Nave Solar
Nave Solar
2011
Nave Solar is an interactive installation featuring a fake Sun that is activated by the pendular motion of the public as they hang from a rope and swing along the nave of a 16th Century catholic inquisition church. Using tracking systems, the installation detects the motion of participants and generates smoke that accumulates on the ceiling of the apse as well as activates the Sun's flares, surface turbulence and sun spots.

Microphones
Microphones
Subsculpture 10, 2008
"Microphones" is an interactive installation featuring one or several 1939-vintage Shure microphones, placed on mic stands around the exhibition room at different heights. Each microphone has been modified so that inside its head is a tiny loudspeaker and a circuit board connected to a network of hidden control computers. When a public member speaks into a microphone, it records his or her voice and immediately plays back the voice of a previous participant, as an echo from the past. View Details.
Apostasis
Apostasis
2008
An interactive installation featuring powerful robotic searchlights that create static columns of light in a dark room. When someone tries to walk into a light beam, a computer automatically moves the searchlight so that the beam is pointed somewhere else on the room. A video tracking system observes the room and makes sure that the lights are always illuminating empty spaces where there is no one. People may continually attempt to enter the spotlight but the system will adapt to ensure this can never be achieved. View Details.
Pulse Park
Pulse Park
Relational Architecture 14, 2008
"Pulse Park" is comprised of a matrix of light beams that graze the central oval field of Madison Square Park. Their intensity is entirely modulated by a sensor that measures the heart rate of participants and the resulting effect is the visualization of vital signs, arguably our most symbolic biometric, in an urban scale.

Amodal Suspension
Amodal Suspension
Relational Architecture 8, 2003
"Amodal Suspension" is a large-scale interactive installation where people can send short text messages to each other using a cell phone or web browser. However, rather than being sent directly, the messages are encoded as unique sequences of flashes with twenty robotically-controlled searchlights, not unlike the patterns that make up Morse code. Messages "bounce" around from searchlight to searchlight, turning the sky into a giant switchboard. View Details.
Bifurcation
Bifurcation
Shadow Object 2, 2012
A small Y-shaped branch, similar to a divining rod, is suspended from a thread and moves with the air flow and with a small motor. Projected on the wall behind the branch is its shadow, only you can see the entire tree from where the branch came. The branch and the tree shadow are always oriented in the same way. View Details.

Semioptics for Spinoza
Shadow Object 4, 2012
A plano-convex lens is suspended from a thread and moves with the air flow and with a small motor. Projected on the wall behind the lens is a set of artificial lens flares generated by equations that take into account the orientation of the lens in relation to the viewing public. The project generates fake light beams that go through the real lens: the lens then diffracts and scatters the fake light creating light source aberrations, directional haze and chromatic distorsion.

First Surface
First Surface
Shadow Object 3, 2012
Two front surface mirrors are suspended from a thread and move with the air flow and with a small motor. Projected on the wall behind the mirrors is a real-time virtual representation of the public as seen from the perspective of the mirrors. The public is represented as patterned 3D silhouettes anchored in a reference prism that rotates with the mirrors. The piece is an attempt to construct an artificial perspective on the reflected subject. View Details.
Sitestepper
Sitestepper
Relational Architecture 10, 2004
"Sitestepper" is an Internet program that shows a 3D view of an apparently "neutral" living room. This space can be transformed automatically by scanning a website to extract its images, texts, colours and sounds. The system analyzes the contents of the submitted webpage and uses them to furnish and decorate the room, "branding" the space with a layer of live media. This project was commissioned for LA MOCA's digital gallery. View Details.
Friendfracker
Friendfracker
2013
Friendfracker is a service that automatically deletes a set of friends from your Facebook account. Upon authenticating your data on the website, the service deletes 1 to 10 friends at random. The project was developed with Harper Reed for Rhizome's 7 on 7 conference. View Details.
