ABSTRACT:
An apparatus is described for projecting a motion picture image on a screen that extends 360.degree. around the viewers, by moving a film past a slit through which light shines, forming an image of the slit on the screen, and rapidly revolving the slit image around the screen. The film moves rapidly enough to permit the projected slit image to rotate around the screen at a rate of at least about 50 rotations per second. The film, which moves continuously, can be free of sprocket holes and can be driven by a capstan drive, and the film can have a thickness less than half the thickness of present film stock so that a roll of film of moderate diameter can last several minutes.
