Border Tuner / Sintonizador Fronterizo
Relational Architecture 23, 2019
"Border Tuner" is a large-scale, participatory art installation designed to interconnect the cities of El Paso, Texas, and Ciudad Juárez, Chihuahua. Powerful searchlights make “bridges of light” that open live sound channels for communication across the US-Mexico border. The piece creates a fluid canopy of light that can be modified by visitors to six interactive stations, three placed in El Paso and three in Juárez.

Bilateral Time Slicer
Bilateral Time Slicer
2016
“Bilateral Time Slicer” is a biometric tracking system that finds the axis of symmetry of members of the public and splits a live camera image into two slices. With each new participant time slices are recorded and pushed aside. When no one is viewing the work, the slices close and rejoin creating a procession of past recordings.

Zoom Pavilion
Zoom Pavilion
2015
“Zoom Pavilion” is an interactive installation that consists of immersive projection on three walls, fed by 12 computerized surveillance systems trained on the public. The piece uses face recognition algorithms to detect the presence of participants and record their spatial relationship within the exhibition space. Independent robotic cameras zoom in to amplify the images of the public with up to 35x magnification: the zooming sequences are disorienting as they change the entire image "landscape" from easily recognizable wide shots of the crowd to abstract close-ups. Zoom Pavilion marks the first collaboration between artists Rafael Lozano-Hemmer and Krzysztof Wodiczko.

Pulse Corniche
Relational Architecture 22, 2015
“Pulse Corniche” (Relational Architecture 22) was an interactive canopy of powerful light beams projected into to the sky by robotic searchlights whose brightness and orientation was controlled by the heart-rate of visitors to the Abu Dhabi’s Corniche. People were free to participate by holding a sensor placed in the centre of the plaza that converted the electrical activity of their heart into a unique lighting sequence. The intensity and direction of the lights visualized the different biometric rhythms of each participant, in an urban scale.

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.

Voice Tunnel
Voice Tunnel
Relational Architecture 21, 2013
“Voice Tunnel” (Relational Architecture 21) was 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.

Voice Array
Subsculpture 13, 2011
In “Voice Array” (Subsculpture 13), 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.

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.

Please Empty Your Pockets
Please Empty Your Pockets
Subsculpture 12, 2010
“Please Empty your Pockets” (Subsculpture 12) 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.

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.

Less Than Three
Less Than Three
2008
"Less than Three" is an interactive installation of light strips that form a network between two intercoms. As a participant speaks into an intercom, their voice is translated into corresponding flashes of light and this light pattern is transmitted visually along one of the several possible pathways through the network. When it reaches the other side, the viewer's phrase is once again released as sound. Several voices can be carried simultaneously and the short contributions going fast through the network and the longer ones taking longer.
