This site shows a collection of stereograms that I have made in the Netherlands in 1995. Sterograms are photographs (or computer renderings) that allow the viewer to have a spatial experience, although the picture is flat. In order to see them properly, you have to focus your eyes to a different picture each. In any ordinary situation, the eyes do not perform this trick, but it can be learned without much difficulty. You either have to look at the screen while keeping your eyes parallel, like if you were looking at a very distant object, for example looking out of the window (straight looking) or look at the screen while keeping your eyes crossed, like if you were looking at a very near object, for example the tip of your nose (cross looking). Cross looking is easier to accomplish in the beginning, but straight looking causes less strain in the eyes and makes the stereogram appear larger than it is (which is good).
On the training graphic below, try to make the squares overlap. The central ring should then appear to float above the other two rings. Start with the smaller pictures (150x150) and allow your vision some time to ajust. Then click on the link to the left to see the actual photographs. The training graphics represent the actual size of the photos you get to see after clicking the link.
