An apparatus for providing stereoscopic effects includes a cassette and a projector. The cassette defines a chamber for enclosing tow strips of film. A first passage is in communication with the chamber and diverges into two second passages so that an edge is formed between the second passages. A first gear is mounted below the chambers. A second gear is engaged with the first gear. Two separate wheels are co-axially linked to the second gear. A plurality of teeth radially project from each wheel. The teeth engage with perforations which are defined in strips of film. When the first gear is rotated, the strips of film are fed from the chamber along the first passage by means of the wheels. The strips of film are then separated from each other by means of the edge and are respectively fed along the second passages. The projector has two pairs of transparent panels which define two third passages which are in communication with the second passages. Two chambers are in communication with the third passages for containing the strips of film. Two light sources project light through the pairs of transparent panels for providing illuminated images. The projector further uses two lenses through which light passes.
