<p>A projection system for a theatre in the round having a plurality of moving image projections. The projectors can be either film projectors or television-type projectors. They project in an essentially cylindrical surface (20A) which is viewed by people at a viewing location. A lens (22A) is associated with each moving image projector, the lens having an optical axis located at or above a top edge (16) of the viewable portion of the cylindrical surface. A source of moving images (24) is associated with each lens, the center of which source is located above the optical axis of the associated lens such that moving images are projected by each lens downwardly toward a portion of the essentially cylindrical surface in an essentially distortion-free manner.</p> |
