Patent number: 5980043Abstract: One type of kaleidoscope has an object cell that contains a multitude of small objects immersed in a viscous liquid. By inverting the object cell, a user can enjoy a continuous ever-changing display of pleasing and colorful symmetrical images as the objects cascade through the viscous liquid under the influence of gravity. Eventually the objects settle to the top or bottom of the object cell as determined by their densities, and the viewer needs to invert the object cell again. It is desirable to prolong each cascade so as to reduce the frequency with which the object cell must be inverted. Several ways of accomplishing this are disclosed. The walls of the cell may converge and may be provided with bumps or other surface irregularities. The movement of the objects may be impeded by the provision of fixed obstacles within the object cell. In another approach, an upwelling and circulation of the viscous liquid is produced by a simple pump that is mobilized by inverting the object cell.Type: GrantFiled: February 11, 1998Date of Patent: November 9, 1999Assignee: Jaesent, Inc.Inventor: Jacob Y.

Patent number: 5132844Abstract: 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.Type: GrantFiled: November 18, 1991Date of Patent: July 21, 1992Inventor: Evert Sharp, Jr.
