CENTURY OF LIGHT (1980) is the world's first large public permanent electronic interactive sculpture. Shown here responding to a dance performance, was located in downtown Detroit. It was a suspended 18 foot (5.5 meters) diameter mandala of 144 one foot (30 cm) diameter light spheres displaying computer animated patterns.

The sculpture generated the patterns in response to the movements of people around it. It used micro-wave radar and a photocell for input information. The PROGMOD is a programming module that electronically duplicates the Century of Light.
