I've always been fascinated by illusion in images and sculpture, and for the past couple of years I've been experimenting with sterescopic photographs - a pair of photos taken one for each eye which when viewed in a certain way merge into a single image which reads in 3D. I've added a few of these pairs here.
These are arranged for cross-eyed viewing, which many people can easily learn to do:
sit back a bit, go cross-eyed until a third image appears between the pair, and gaze into that one without changing your focus. After a day or two of eye ache it gets easier.
Holding a finger up near your face to focus on can help, and your distance from the screen depends on the size. Another way is to put dark dots, one centrally at the top of each image, gaze at these and go cross-eyed enough to bring them together in the centre, then simply look down at the 3D image.
It's possible to get Stereoscopes, viewers with prismatic lenses and for those you need to separate the two images and switch them over.
