Abstract:
Apparatus for displaying multiple series of still images, each said series forming an animated display to a viewer moving substantially at a known velocity relative to said multiple series substantially along a known trajectory substantially parallel to said multiple series, said apparatus comprising:a backboard having a backboard length along said trajectory, still images of each said series interspersed with still images of other said series and mounted on a surface of said backboard, each still image having an actual image width and an image center, image centers of successive images of a same series being separated by a frame-to-frame distance; and a slitboard positioned substantially parallel to said backboard facing said surface thereof and separated therefrom by a board-to-board distance, said slitboard being mounted at a viewing distance from said trajectory, said board-to-board distance and said viewing distance totaling a backboard distance, said slitboard having a slitboard length along said trajectory, and having a plurality of slits substantially perpendicular to said slitboard length, each said slit corresponding to a respective image of each series and having a slit width measured along said slitboard length and a slit center.
