ABSTRACT:
A novelty shadow projecting lamp is disclosed having at the center a light source contained in a protective enclosure. A portal or opening lets light escape in a predetermined direction, and is in visual communication with and surrounding a light source enveloped by a bi-phased liquid. The bi-phased liquid includes bits of meltable wax. A heat source located in the base portion of the lamp, is in thermal communication with the liquid. As the heating element melts the wax, which is suspended in the liquid, the wax melts and floats freely in the liquid, thereby passing through the light source and casting shadows onto walls and surrounding area.
