  • Ornamental sphere
    Patent number: 6877883
    Abstract: An ornamental sphere includes a base and a transparent or translucent sphere mounted on the base. The sphere is completely filled with rheoscopic fluid. A driving apparatus within the sphere is energized to agitate the rheoscopic fluid to thereby create currents or movements that are visible to an observer through the sphere. In addition, a light source is mounted within the sphere to illuminate the rheoscopic fluid and enhance the appearance and visibility of the current movement. The light and/or the driving apparatus can be activated by a plurality of systems. Alternatively, the sphere can be filled with two immiscible fluids having different refractive indexes.
