1. A system and device for enhancement of depth perception in a viewer of a two-dimensional image comprising: a) a two-dimensional image with one or more monocular depth cues displayed on an image surface; and b) at least one visually identifiable object placed in front of said image surface to create a combined scene with said two-dimensional image, said visually identifiable object being: 1) substantially within the depth of field of focus of said viewer's eyes when said two-dimensional image is in focus for said viewer, 2) without substantially interfering with the view of the viewer of said two-dimensional image, and 3) a sufficient distance from the two-dimensional image to induce disparate binocular retinal images in the eyes of the viewer; having the effect of enhancement of the viewer's depth perception in viewing said two-dimensional image by and/or with the fusion of said binocular images of the combined scene in the viewer.
