The Trammel of Archimedes

The Trammel of Archimedes can serve as a device to draw elipses, and as the Kentucky DoNothing, it can entertain you briefly. It also perfectly illustrates the interactive dance of two objects of differing gravity—or a Tai Chi exponent taking advantage of his opponent's center of gravity. In the animation, the black square is the "handle."
