Patent ID: 8708767

Claim:
A method of illuminating a toy object with ultraviolet light to create a colorful light display, the method comprising: providing an object having at least one ultraviolet sensitive layer that forms a pattern wherein the ultraviolet sensitive layer is transparent such that the pattern is hidden from view in the absence of ultraviolet light; illuminating the at least one ultraviolet sensitive layer with ultraviolet light using the at least one light source, the at least one ultraviolet sensitive layer arranged to absorb the ultraviolet light and emit a colored light in response such that the previously hidden pattern is revealed, the at least one ultraviolet sensitive layer, when not exposed to the ultraviolet light, being arranged not to emit the colored light; increasing and decreasing the intensity of the ultraviolet light repeatedly, thereby causing the intensity of the emitted colored light to also increase and decrease; and generating sound at a speaker and synchronizing the sound with changes in the intensity of the emitted colored light.
