Abstract
A rotating turbulent display device is disclosed as comprising a transparent display cell having an outer surface and an inner chamber which may be filled with various substances and structures including liquid, granular particles or a rigid member adapted to displace the substances within the inner chamber of the display cell. The device is mounted within a base unit having a complementary aperture for receiving the outer surface of the display and a motor therein which operates to rotate the display cell at a predetermined rotational speed and direction to simulate the passage of time thereby creating a visible flow pattern within the inner chamber of the display cell.
