Abstract

An illuminable user interface includes a plurality of input elements, a source of light energy, and a fiber optic filament mat provided with irregularities arranged in one or more controlled patterns to thereby form one or more visible images when the fiber optic filament mat is illuminated by the source of light energy. The one or more visible images are positioned relative to the input elements to convey information concerning the input elements.
