Abstract: A three-dimensional display device for commercial advertisement and science museum displays is disclosed. Three-dimensional elements are stacked horizontally or vertically along a stationary shaft around which they rotate, and are coupled together in such a way that they perform as a torsional wave medium and chaotic system. Display surfaces can be attached to the three-dimensional rotatable elements such that mirrors, text, imagery, and products can be viewed as the elements rotate. The rotatable elements can be spun by hand. Alternatively, servo motors and computer control permit the device to be choreographed and synchronized to an accompanying audio track.

Abstract: A device provides temporal and spatial 3-D patterns with a plurality of elements. The shape, position and orientation of the elements are controlled by a computer. The medium in which the elements lie provide movement of the elements without effects of vibration or turbulence. In a particular medium elements movements are dampened such that a quick change in position and/or orientation of an element is without apparent vibration. The medium and elements are of respective materials such that noise is eliminated. Iron powder elements on a surface are repositionable and reorientable in a desired temporal and spatial pattern through computer controlled changes to a generated magnetic field. Different sized bubbles are generated in a desired temporal and spatial pattern in a tank of glycerin through computer controlled air valves. The computer control is preprogrammed or in response to user operation of an input device.
