The invention is similar to a kaleidoscope, but substantially only as to its use. In the embodiment depicted and described, it comprises a cylindrical housing having a rotatable end cap journalled thereon, with a window or eyepiece at one end of the housing and an objective, disposed for viewing, in the rotatable end cap. The objective, however, is a single, variegated disc, and within the housing are light-transmitting rods which rotatably scan the disc and conduct light images from the objective toward the eyepiece. The images, albeit variegated, are asymmetrical rather than symmetrical (as in a kaleidoscope). Further, the inner wall of the housing has a layer of striated, light-reflective, plastic material thereon which, as the end cap is rotated, causes helical, cascading waves of variegated light to appear within the housing.
