An assembly is provided which employs a light source that directs slightly convergent light rays of visual frequencies towards a first polarizing means. The first polarizing means polarizes the light rays and directs them towards a first lateral face of a transparent, pyramidal object, and/or towards a reflecting means which in turn directs the received light rays towards the base of said object. Said object must display birefractive properties, and must have at least four optical axes. Upon encountering said object, a portion of the light rays enter into said object and eventually, many of the light rays unite on any one of several optical paths that extend from a second lateral face and/or the base of the object in a convergent fashion. The united light rays create interferences on each of said optical paths. A combination of said converging optical paths creates an interference pattern. By viewing said second lateral face and/or base of the object via a second polarizing means, the interference pattern can be visually perceived. Depending on the specific arrangement of the components of the present invention, a viewer can visually perceive an interference pattern that resembles a two-eyed winged structure, a scarabus beetle, or a pharaoh's head.
