Pulse Spiral

Rafael Lozano-Hemmer

Sensor handles beneath a towering array of lightbulbs detect a visitor’s heartbeat and the lowest bulb flashes to its rhythm. As new recordings are added, old ones move up the spiral. Over time, the internal rhythms of hundreds of users are displayed. The lightbulbs are arranged in a spiral paraboloid according to Fermat's equation; an extraordinary spatial distribution found in nature.
