I have been interested in extending the realm of 2D images to include motion (kinetic images) as well as another (third) dimension. I stumbled across this 3D effect (in the image) in the last few days. The idea was to merge unrelated images, one of which had an amorphous structure (to allow the unconscious a change to come into play when collaging). I was shocked to discover that the collage creates an illusion of depth due in part to the contrast between the stars and the black background. collage of image with starfield (Original unenhanced image courtesy Hubble Space Telescope).
