Optical image multiplying device

Abstract

An optical image multiplying device includes an object cell containing a plurality of tumbler objects, each of which carries a pictorial image on a selected region thereof. The pictorial region of each object includes transparent portions which permit the viewer to see detail of the objects behind it. The pictorial regions are surrounded by transparent regions that permit the individual images or distinctive parts thereof to become periodically quite recognizable as the objects tumble relative to one another. Additionally, placement of the pictorial regions on geometrically different parts of their respective tumble objects enhances periodic recognizability. A selected region immediately adjacent, and possibily surrounding the pictorial region is provided with transparent color, but a portion of at least one tumbler object is preferably clear. A number of generally transparent beads, typically clear or of primary colors in a subdued tone may be included in the object cell. While these beads do not permit the viewer to discern details of objects behind them, their outlines can be seen and the beads pick up color of the objects through which they are viewed. Thus, the beads may at different times appear as different colors and the viewer is sometimes able to detect a change of color as the bead moves across the boundary between regions of different color.
