Abstract
A multimedia presentation system a projector to project images toward an audience. A plurality of nozzles are partially submerged in a body of water at locations between the projector and the audience. The plurality of nozzles are located at different distances from the projector. Each of the plurality of nozzles is arranged to produce a fan like water mist onto which the projector projects images. A controller is coupled to the projector and the plurality of nozzles. The controller causes the projector to project images and at least one of the plurality of nozzles to produce a water mist in a synchronized sequence such that the images appear at different distances from the projector at different times. The controller may further control the orientation of each nozzle to vary the distance by inclining the plane of the water mist relative to the surface of the body of water.
