Abstract
A method and apparatus for illumination and entertainment by light emitted from a guide via scattering provides a new form of visible lighting. An illumination source is coupled to an optical guide to produce a beam within the guide. The beam is disrupted by a emitting surface which may have design features embedded thereon. The disruption causes scattering of the beam, producing an illuminated body. The disruption may be a matte coating on a side wall of the guide, a lens with a matte image thereon at the end of the guide, or other discontinuity that results in an entertaining or pleasing illumination pattern.
