Pulse Park

Last night I checked out Pulse Park, in Madison Square Park.  It's an interactive art piece by Rafael Lozano-Hemmer and it's pretty cool.

Observers place their hands on a pair of sensors (like you'd find on a machine at the gym), and then 200 ETC Source 4 luminaires pulse to the person's heartbeat:

(You can hear the generator loading down on each pulse).

When the audience member lets go, their heartbeat is added to the previous 200, and they sequence on one at a time and then mix together:

It runs until November 17th, stop by and see it if you can!
