Abstract
A sculptured optical art form device and the method of making comprising a transparent block having a predetermined index of refraction to provide internal light reflection, said block having a cavity disposed in one wall, the cavity being shaped or carved as a symmetrical one-half of an object that is optically displayed as a whole object in the block. The transparent block may be constructed of an acrylic polymer or glass. The geometrical outside shape of the block is selected to provide an optical view through at least one wall to an observer such that light rays striking the wall having the cavity are internally reflected. The observer looking through the viewing wall will observe a complete, fully formed object optically created by the symmetrical one-half cavity formed in the block wall providing internal optical reflectance. In one embodiment, the object optically created by the cavity appears to be completely embedded in the center of the block.
