A pendulum is supported on a trapezoidal frame that may be rotated at constant speed by a friction wheel in contact with the lower base. A camera mounted on the axis of rotation transmits an image of the swinging pendulum bob to a nearby monitor. The camera may by the flick of a lever either rotate with the rotating frame or be locked so that it is in a fixed frame of reference. The path followed by the swinging pendulum can be viewed in either of the two frames. The straight line motion of the pendulum produces a varied selection of curved traces in the rotating frame.
