1. An interactive display device comprising:
a touch sensor layer;
a light layer comprising a plurality of light elements configured to render digital information; and
a substantially transparent insulation layer arranged between the touch sensor and light layers, wherein the insulation layer is a solid layer having no apertures;
wherein the touch sensor layer comprises a conductive material arranged on a top surface of the insulation layer,
wherein the device is configured to be positioned directly beneath a non-transparent surface layer with the touch sensor layer proximate to a bottom surface of the non-transparent surface layer, and
wherein the light layer is not visible beneath the non-transparent surface layer when the light layer is inactive and is visible beneath the non-transparent surface layer when the light layer is active.
