“Pulse Park” is an installation in New York City’s Madison Square Park by Mexican-Canadian artist Rafael Lozano Hemmer that attempts to visualize the collective heartbeats of pedestrians around the park. You “register” at a kiosk by holding a sensor to record your heartbeat which is then translated into light into one of 200 individual lights circling the park. The result, as can be seen in the video, is a collective aura of light pulses that can be seen throughout the local neighborhood.
