CENTURY OF LIGHT (1980), shown responding to a dance performance, was located in downtown Detroit. It was a suspended 18 foot (9 meters) diameter mandala of 144 one foot diameter light spheres displaying computer animated patterns.

The sculture generated the patterns in respose 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.
