Abstract
First and second half or associated objects, in respective different sequential positions are aligned behind respective adjacent, first and second, inclined faces of an optical prism so that, when viewed at different angles alternately through a front face of the prism, images of the first and second half objects are seen alternately by transmission and total internal reflection at alternate faces, combining to form completed whole images of first and second objects alternatively, thereby providing an impression of animation by object movement. The half objects can be pictures of half of a same or similar face or person having respective different expressions producing a changing expression or hands producing a clapping effect. Written message portions associated with half objects can form a complete message/slogan when viewed at alternate angles. The optical prism can be solid or liquid filled and embodied in picture frames, domestic utensils or personal accessories/apparel.
