1. A display apparatus comprising:
- a light source, a vessel containing a supply of a light-transmitting liquid having an upper surface at a predetermined level, a disturbance system for disturbing the liquid surface from thereabove without disturbing the vessel and without significantly changing the predetermined level, and a directing structure directing light from the source through the liquid and then through the liquid surface and then onto a display surface spaced from the vessel for projecting onto the display surface a visual wave pattern which moves in accordance with disturbance of the liquid surface.

Abstract
A display lamp includes an electric light bulb disposed within a cylinder supported in a substantially vertical orientation. A light-transmitting container of water or other light-transmitting liquid is supported on the top of the cylinder. A dispenser of liquid is disposed above the container for dropping droplets of liquid onto the surface of the liquid in the container for disturbing it. The light shines through the vessel and the liquid and its disturbed surface and onto an associated display surface, such as an adjacent wall or ceiling, for producing thereon a visual wave pattern which moves in accordance with the disturbance of the liquid surface.

14. A method of producing a moving visual wave pattern on a display surface comprising:
-
providing at a location spaced from the display surface a vessel containing a supply of a light-transmitting liquid having an upper liquid surface at a predetermined level, disturbing the liquid surface without disturbing the vessel, and without significantly changing the predetermined level, and while the liquid surface is being disturbed directing a light beam through the liquid and then through the liquid surface for projecting onto the display surface for projecting onto the display surface a visual wave pattern which moves in accordance with the disturbance of the liquid surface. - View Dependent Claims (15, 16, 17, 18)
