ABSTRACT:
A kaleidoscope composed of two or more mirrors housed within a tubular container, an eye-piece at one end of the tubular container for viewing the kaleidoscopic design, and a translucent or transparent screen located at the end of tubular container that is opposite the eye-piece. The screen is capable of being rotated, in a plane orthogonal to the longitudinal axis of the kaleidoscope, about one or more axes. The screen is also capable of being translated in said plane. The screen is adapted to be written upon erasably with pens, pencils, paint, or the like. The screen is also adapted for adhesively holding translucent or transparent paper for the purpose of writing thereon. The tubular container contains a compartment for storing pens, pencils, and so on. This kaleidoscope allows one to produce symmetrical and beautiful designs from simple drawings and allows the user to cooperate interactively with the kaleidoscope.
