Abstract
An illuminated rock and method having the external appearance of a rock and having a light source inside which transmits light through openings in the rock to an outside viewer. Preferably, the light passes through a diffusion screen so as to obscure the actual light element from view, while allowing sufficient light to pass through the design. It is preferred that the design be in the form of a street number, with the illuminated rock being placed proximate a front portion of a home so that the street number may be viewed at night.
