ABSTRACT:
The present invention relates to a projecting kaleidoscopic system for viewing kaleidoscopic images on a screen external of a conventional kaleidoscope. In one form, the system includes: (i) a high intensity lamp; (ii) a conventional kaleidoscope positioned in optical alignment with the lamp and including a tube of circular cross section having a longitudinal axis of symmetry, an eye piece at one end and an object box at an opposite end, the box including transparent wall means pointed at the lamp defining a cavity means filled with a multiplicity of loosely assorted pattern producing objects and reflector means within the tube between the eye piece and the transparent wall means wherein the tube, eye piece and object box provide a kaleidoscope that is a separately marketable unit product in and of itself; (iv) drive means mounted in frictional contact with the kaleidoscope for sole support thereof held in such contact by gravity alone wherein the kaleidoscope as a separately marketable unit can be evaluated, the drive means rotating the kaleidoscope about its axis of symmetry at relatively low RPM; (iv) optical lens and focusing means external of the kaleidoscope for optically receiving, enlarging and projecting the kaleidoscopic images appearing at the eye piece; and (v) a rear projection screen means external of the kaleidoscope for viewing the images whereby group viewing is enjoyed.
