Abstract
A decoration structure, especially a decoration for a room, has a frame structure bounding an opening within which to present to view a background element bearing first subject matter, such as a scene or an abstract design, and a foreground element through or past which the background element can be viewed, the foreground element being spaced sufficiently from the background element to be clearly spaced to the viewer and so as to cause an apparent relative movement when there is relative movement with respect to the viewer. Illumination is provided for at least the background element. One or both of the elements may have small colored zones in a transparent or translucent sheet for change of transmitted color, to the viewer, as relative movement occurs.
