ABSTRACT:
Methods and apparatus provide for Reveal. Reveal includes a lens and a light source mounted within a housing. The light source projects light through the lens onto a projection surface. A first slide, a second slide and a motion slide are mounted in the housing between the light source and the lens. The first slide causes light from the light source to project a first defined image upon the projection surface. The second slide, which is less focused than the first defined image, causes light from the light source to project a second defined image upon the projection surface. The motion slide includes motion elements movable in response to a stimulus, such as airflow. Movement by the motion elements introduce an interference in light cast by the light source onto the projection surface. The interference provides an appearance of movement of an image projected by the second slide.
