ABSTRACT:
A light show projector is provided for use in producing a pleasing and variable laser-like visual line pattern on a wall or the like in synchronized relation with an audio input signal such as music. The light show projector comprises a compact and portable housing having a substantially point light source projecting a narrow light beam through a rotatable color wheel having multiple radial segments of different colors, and further through an adjustable focusing lens for reflection by a dynamically supported mirror onto a wall or ceiling of a room for viewing. The mirror is resiliently supported by asymmetrically arranged support members, one of which is electromagnetically displaced in relation to selected characteristics of the audio input signal, thereby producing a multidimensional mirror displacement yielding a large and widely variant esthetically attractive laser-like line pattern. The appearance of the line pattern is enhanced by variably driving the color wheel in relation to other characteristics of the input signal to produce a changing multicolored display for observation while listening to music.
