Abstract
The present invention is directed a projection system that produces a visual special effect. In one embodiment, the system includes a projector, a translucent projection substrate, a flow disturbance structure associated with one side of the substrate, and a water system for distributing water over the side of the substrate with which the flow disturbance structure is associated.
Claims20
A projection system comprising:
- a projection substrate comprising a front side from which a viewer views an image, a back side from which a viewer does not typically view an image, and a flow disturbance structure for causing water that travels over at least one of said front side and said back side to have a rippling characteristic;
- a water system for providing water to flow over at least one of said front side and said back side of said projection substrate so as to interact with said flow disturbance structure;
- and
- a projector for projecting an image towards said projection substrate comprising a lamp and an image holder for placing an image between said lamp and said projection substrate.

A projection system comprising:
- a translucent projection substrate comprising a front side from which a viewer views an image, a back side from which a viewer does not typically view an image, and a flow disturbance structure for causing water that travels over at least one of said front side and said back side to have a rippling characteristic;
- a water system for providing water to flow over at least one of said front side and said back side of said translucent projection substrate so as to interact with said flow disturbance structure;
- and
- a projector for projecting an image towards said projection substrate comprising a lamp and an image holder for placing an image between said lamp and said translucent projection surface.

A projection system comprising:
- a translucent projection substrate comprising a front side from which a viewer views an image, a back side from which a viewer does not typically view an image, a top end, a bottom end, and a flow disturbance structure for causing water that travels over one of said front side and said back side to have a rippling characteristic;
- a water system for providing water to flow over one of said front side and said back side so as to interact with said flow disturbance structure;
- and
- a lighting structure for projecting light at an angle to one of said front side and said back side such that, during operation, water traveling over one of said front side and said back side with said rippling characteristic is engaged by light from said lighting structure.

A projection system comprising:
- a translucent projection substrate comprising a front side from which a viewer views an image, a back side from which a viewer does not typically view an image, a top end, a bottom end, and a flow disturbance structure for causing water that travels over said back side to have a rippling characteristic;
- a water system comprising a water manifold located adjacent to said top end of said translucent projection substrate and for distributing water over said back side of said translucent projection substrate, a water reservoir located adjacent to said bottom end of said translucent projection substrate, and a pump for moving water from said water reservoir to said water manifold;
- a lighting structure for projecting light at an angle to said back side of said translucent projection substrate such that, during operation, water traveling over said back side and having said rippling characteristic has brightness variations over said translucent projection surface;
- and
- a projector for projecting an image towards said back side of said translucent projection substrate comprising a lamp, a lens, and an image holder for placing an image between said lamp and said lens.
