ABSTRACT:
A device displaying a changeable image. The device includes a screen having a viewing plane, and platelets thereon. The platelets cast shadows of different sizes. The shadows, when viewed collectively, form images on the viewing plane. The platelets are made of a rigid opaque material and are attached immovably to the viewing plane, the platelets are disposed in parallel rows extending in two mutually perpendicular directions, each forming an angle of 45.degree. with the horizon. The platelets extending in the respective directions are different in both size and shape, such sizes and shapes being determined so as to form a different image in each direction by the shadows cast by the platelets.
