Concentric Pendula ReturnToPortfolio Next Sculpture
Concentric Pendula

This machine was built as a mobile exhibit for the Curiodyssey Museum at Coyote Point in Burlingame California. The idea is classic: pendula which weigh the same but are closer or further from their fulcrum will swing at different rates, and when you put a series of them in line, some wonderful patterns emerge. This is obviously a much more complex illustration of the principle. Each of the disc pendula have a pull-knob below which can be pulled and released to activate it. The tall lever at the right can be pulled to activate all pendula at once.
