    Patent number: 4531318
    Abstract: A thin disk contrastingly colored on opposite sides is rotatably mounted to rotate about its diameter. A permanent magnet on the disk allows the disk to be driven by a pair of reversibly magnetizable cores. One of the cores is bent to provide a stop which limits the rotation of the disk in either direction. The two limiting positions correspond to the display of the contrastingly colored sides in the viewing direction.
