Projecting onto an upper surface of a body of water

A display system, comprising:

• an open container for receiving a volume of a liquid;
• a wave generator system operable to create a projection screen by creating a surface roughness on an area of an upper surface of the liquid, whereby light is reflected back from the upper surface;
• and
• a projection assembly focusing light into the open container onto the created projection screen,
• wherein the wave generator system creates rows of waves providing the surface roughness in the area of the upper surface.

A method of projecting on a translucent surface of a body of water, comprising:

• positioning a surface agitation assembly in or proximate to the body of water;
• operating the surface agitation assembly to form a projection screen in a portion of an upper surface of the body of water;
• and
• projecting light upon the portion of the surface of the body of water, whereby at least a portion of the light is reflected to an observer due to an increase in a surface roughness of the upper surface by the surface agitation assembly,
• wherein the surface agitation assembly comprises a wave generator system and wherein the wave generator system comprises first and second wave generators creating a cross-hatch pattern of waves in the portion of the upper surface to form the projection screen.
