Twisted Donut is a piece of kinetic art. It has no other use. Twisted Donut starts its transformation as a donut (torus) shape. By twisting the parts, the shape becomes stretched into a line before twisting back into a donut. Especially the intermediate helical shapes are quite pleasing. The whole transformation is achieved with a hidden gearing mechanism.
