ABSTRACT:
A color changing display in which various elements and portions of the display are formed as shallow transparent pockets on a supporting back panel. Each pocket is connected in a closed fluid circuit to an individual reservoir containing a suitably colored fluid. Actuating mechanism is used to raise and lower each reservoir individually so that fluid can flow into or drain out of selected pockets in any desired sequence or timed program. The result, viewed from the front through the transparent pockets, has the appearance of a display building up in a particular sequence or changing color in various patterns.
