Abstract
A visual display in which written, pictorial or combination thereof may be presented for viewing in an appealing manner for any of a variety of purposes, and apparatus for developing changes and/or animation in the display utilizing specially prepared transparent media by which the subject matter is presented and means to control the visual presentation of that subject matter and obtain change and/or animation effects.
Claims3
A method of displaying in sequence subject matter in differing visual appearances, the method comprising:
- providing separate pictures of the differing visual appearances of subject matter to be displayed;
- reproducing each separate picture one at a time on a light transparent sheet with each such picture reproduced thereon in a plurality of finite portions spaced apart from each other such that the finite portions of each picture are arranged in a plurality of rectangular patterns in which each picture has its finite portions located in the same position in each of the rectangular patterns, and the rectangular patterns are repeated over the area of the light transparent sheet in a rectangular order having horizontal and vertical relationships, the finite portions of each picture being spaced in horizontal and vertical alignment so that the collective finite portions of each picture are displayed at the same time;
- providing a source of illumination for the transparent sheet;
- sequentially limiting the illumination to display all of the finite portions of one picture at a time, and proceeding through the illumination of each subsequent picture;
- and repeating the illumination of each picture always proceeding in the same horizontal and vertical direction of alignment of the respective finite portions.

In apparatus presenting a visual display of subject matter in differing appearances, the improvement which comprises:
- a light transparent sheet carrying finite areas of a plurality of differing appearances in which the finite areas of each appearance are interspersed with the other finite areas in a predetermined rectangular order of interspersal;
- a source of illumination adjacent said transparent sheet for illuminating said differing appearances;
- and operative means in control of said source of illumination for limiting the illumination of said finite areas to the separate collective display of one differing appearance at one time and in said predetermined rectangular order such that each collective differing appearance from a first to the last is illuminated and is repeated always in the same order, said operative means including a frame, means carried by said frame in position such that the finite areas of each differing appearance are collectively prepared for display;
- and rotary means for controlling the source of illumination to conform to said predetermined rectangular order for display of said collective finite areas of each differing appearance.
