Abstract
A rotating display which gives the illusion of simultaneous movement in both the clockwise and counterclockwise directions is disclosed. The rotary display inclues a rotary reflector having a plurality of light reflecting surfaces formed thereon. Each of the light reflecting surfaces is planar and lies in a plane different from each of the reflecting surfaces located adjacent thereto. Means for rotating the reflector about a predetermined axis is provided. A reflective diffraction grating surrounds the reflector and reflects light emitted from a light source onto the reflector and out towards the observer of the display.
