Abstract: An animated game in which opposing players manipulate the respective positions on a viewing surface of a pair of images projected thereon by still projectors. Besides controlling the position of one of the images, each player also selects which of a plurality of images under his control is projected on the viewing surface at any given time. Scoring is provided by circuitry actuated in response to the relative positions of the two images and the particular images selected for projection at a given time. In its disclosed form, the invention employs a plurality of still projectors in two sets, the images from which may be selectively positioned by movement of handles connected to mirrors. Switch means for selection of the image which is projected are incorporated in the handles manipulated by each player.

Abstract: A system for synchronizing projection of a movie film with playback of a sound recording made simultaneously with filming of the movie by simple and economical adapter means compatible with existing camera, projector and sound equipment without substantial modification. The invention utilizes "home movie" type camera and projector equipment, with a tape recorder-playback unit as the sound system. The camera is powered from a power supply having a switch operated by the "play" button of the tape recorder, thereby starting and stopping operation of the camera and tape unit simultaneously during filming and recording. The tape drive motor is powered from a selectively controllable voltage supply, and is not connected to the supply through the normal electrical system of the tape unit, as is conventional.
