Abstract
Embodiments of the present invention use light to add human-like features to an inanimate object. In one embodiment, the object includes a film with an image that has been manipulated to provide for a low profile projection of an image onto a vertical surface directly adjacent to the object. For example, the image of a witch's head could be projected onto a wall and directly beneath, a witch's hat could be hanging on the wall. In another embodiment, changing lights and shadows are used to create animated objects out of otherwise inanimate objects. Various embodiments include components to create the illusion of changing facial expressions. These components include a plurality of light sources and an electronic device that controls the light sources to create the animation.
