Pulse Park

Relational Architecture 14

“Pulse Park” (Relational Architecture 14) was originally exhibited at Madison Square Park, New York City, "Pulse Park" is comprised of a matrix of light beams that grazed the central oval field of Madison Square Park, New York City. The intensity of each spotlight is entirely modulated by a sensor that measures the heart rate of participants. The resulting effect is a visualization of the body's vital signs, arguably our most symbolic biometric, at an immense scale and in an urban setting.

In “Pulse Park,” evening visitors to Madison Square Park have their systolic and diastolic activity measured by a sensor sculpture installed at the North end of the Oval Lawn. These biometric rhythms are translated and projected as pulses of narrow-beam light that will move sequentially down rows of spotlights placed along the perimeter of the lawn as each consecutive participant makes contact with the sensor. The result is a poetic expression of our vital signs, transforming the public space into a fleeting architecture of light and movement.

“Pulse Park” is inspired by Roberto Gavaldón's film "Macario" (México, 1960) in which the protagonist has a hunger-induced hallucination wherein individuals are represented by lit candles, as well as by the Minimalist musical compositions of Conlon Nancarrow, Glenn Branca and Steve Reich. “Pulse Park” is the culmination of a series that Lozano-Hemmer debuted at the 2007 Venice Biennale with “Pulse Room.”
