In a kaleidoscope having an object chamber containing a fluid and containing a number of objects, the objects are caused to move by setting in motion the fluid within the object chamber, using energy derived from a source mounted on the kaleidoscope. In a preferred embodiment, the fluid in the object chamber is set in motion by a small electrically powered pump that is powered by a battery mounted on the kaleidoscope under control of a microprocessor that relates the operation of the pump to the production of lighting effects and sound effects produced within the kaleidoscope. The apparatus results in a display of persistently moving patterns, even when the object chamber remains stationary, and requires no intervention by the user. |
