Dyad Kinetic Sculpture

I built Dyad in 1986 when was experimenting with small freestanding sculptures and random motion. This is a small piece standing about 13 inches tall. It has two independent mechanisms each with its own spring and winder. Each mechanism contributes part of its momentum to the common base motion creating a jerky back and forth rotation. The sculpture only runs for about 30 minutes which was pretty typical for my small sculptures of that time period.
