ABSTRACT:
A wall mounted figure that has swinging legs and arms and a swaying head that continuously moves in dancing movements is constructed with two pendulums with permanent magnets influenced by electromagnetic fields generated by two current-carrying coils. The pendulums operate independently so that the legs and the head and arms swing at different rates to give an appearance of a person dancing the twist.
