Rafael Lozano-Hemmer’s matrix of light beams over Toronto’s harborfront originate from twenty of the world’s most powerful robotic searchlights, and is entirely controlled by a network of sensors that measure the heart rate of passers-by. Up to 20 metal sculptures, with embedded sensors and computers, are placed along the harbor collecting pulse readings from people gripping the sculptures and are then converted into light pulses by computers that determine the orientation of the beams. With over 200,000 watts of power and 15 km visibility, Pulse Front is the world’s largest interactive light sculpture.
