Inspired by the motion of a jellyfish, I built this piece using the tooth of an excavation machine as its base. Above that, a series of mechanisms carries the operators input through a flywheel and several miter gears until it reaches the heart of the machine: the double offset rotating piston. This pison forces the seven umbrella-like arms to spin as they extend and contract, each with a shallow brass dish at the end. Aside from the base and the flywheel, all parts in this machine were designed and fabricated by hand (some with the help of a lasercutter).
