Pulse Park New York, Rafael Lozano

“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. 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.
