Abstract
A method and apparatus for generating a three-dimensional image is provided. The system uses one or more laser beams directed at one or more mirrors. Each mirror is flexibly attached to the vibrating portion of a transducer such as a speaker, the transducer being coupled to a signal source. Suitable signal sources include radio and television tuners, CD players, tape decks, VCRs, musical instruments with suitable signal outputs, and signal generators. The laser beam(s) reflected by the mirror(s) is directed at a rotating viewing surface, the viewing surface being semi-transparent. Due to the rotation of the viewing surface, a three-dimensional image is formed that can be viewed from multiple angles.
