ABSTRACT:
A device for displaying an animated motion picture in which an elongated web of material is provided for receiving images in predetermined, spaced relation. The web may be supported in wound configuration on a reel, and the predetermined, spaced relation of the images is such that the images line up substantially behind one another when the web is wound on the reel. The web has a trailing end disposed at the radially inward end of the winding and a leading end which is disposed at the radially outward end of the winding. The reel is supportable in a generally horizontal orientation to allow unwinding of the web from the reel in a controlled, downward spiral under the influence of gravity, upon release of the leading end of the web, to display the images in rapid succession to present an animated motion picture to a viewer.
