1. A light shape altering device, having elements which selectively modify light, located in the path of a light beam and comprising:

  • a controller which obtains a desired shape for a colored beam of light, and converts said shape into control signals indicative of color components of both said desired shape and colors;

    a first controllable light reflection device, receiving at least part of said control signal, having a plurality of controllable elements, each element defining a portion of an image, and each element being separately controllable between a first state which passes light to a desired object of illumination and a second state which reflects light away from the desired object of illumination; and

    a second controllable light reflection device, receiving at least part of said control signal, having a plurality of controllable elements, each element defining a portion of an image, and each element being separately controllable between a first state which passes light to a desired object of illumination and a second state which reflects light away from the desired object of illumination.
