A picture book, folding card, or card-case, and modifications for larger displays, all of which show film-like
animation, as well as other types of lenticular images, and all of which include embodiments allowing interchangeable images, as well as accommodating standard computer-printer print-outs, which have been made with accompanying
software. In each case, a
mechanical advantage is provided to effect
relative motion between image and overlaying lenticular screen. The images can also be three-dimensional, or any one of many other, well-known lenticular image-types. Various methods of achieving
mechanical advantage, and translation of motion-direction and type are shown, as well as different materials, and manufacturing techniques. Such a family of devices can be used as greeting, or novelty cards, educational or informational books, advertising premiums and displays, and can be wall mounted and / or motor-driven.
