ABSTRACT:
A novel type of liquid filled kaleidoscope with a dual housing that offers the experience of viewing first, a multiplicity of brilliant and symmetrical patterns visible through the eyehole of the kaleidoscopic instrument and second, a kinetic decoration visible from a vantage outside the kaleidoscope along its entire length. Both these effects are created by the same suspended particles flowing freely in a liquid which fills not only the object cell, but also the adjoining chamber located between the inner casing and the interior wall of the transparent main cylinder. This design also allows the viewer to systematically increase or decrease the number of particles visible in the mirrors, by raising or lowering the distal end of the kaleidoscope thus allowing particles to flow into or out of the object cell and the adjoining area. An optical illusion that there is no mirror chamber inside the kaleidoscope can also be created by the dispersion of the same particles against the backrop of a reflective surface.
