Abstract:
1. A system for projecting a shape onto a scene so that the shape appears to emanate from a source location, comprising: a first projection assembly for projecting a first plane of light so that the first plane of light intersects the scene to form a first light stripe on the scene; and a second projection assembly for projecting a second plane of light so that the second plane of light intersects the scene to form a second light stripe on the scene, the first light stripe intersecting the second light stripe for defining a point of light projected onto the scene so that the point of light appears to emanate from the source location; wherein the first projection assembly rotates about a first axis extending through the source location and the second projection assembly rotates about a second axis extending through the source location for controlling the position of the point of light on the scene.
