A novel shadow display apparatus includes a three-dimensional object that is implemented for projecting shadows on a surface when a light source is directed, and which is of an abstract shape such that an observer viewing the object at locations other than at the light source would not be able to identify what the projected shadow would be from the object/structure. A methodology for designing such a shadow display object or structure having an abstract three-dimensional shape, such as the shape of a tree or bush having branch members, and from which an observer viewing the object at locations other than at the light source would not be able to identify what the projected shadow would be from the tree-shaped object or structure. The apparatus may be used for displaying shadow images of symbols, both religious and secular, and may be of any scale.
