Pulse Front, created by acclaimed Montreal-based artist Rafael Lozano-Hemmer is the world's largest interactive light sculpture. A matrix of light beams over Harbourfront, originating from twenty of the worlds most powerful robotic searchlights, 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 Toronto's harbour. Pulse readings, from people gripping the sculptures, are converted into light pulses by computers that also determine the orientation of the beams. With over 200,000 watts of power and 15 km visibility, Pulse Front blends the intimate with the spectacular in one of Toronto's most popular public spaces.
