      If you've stood looking cross-eyed at those stereo pictures made up of seemingly random patterens, but not been able to see a 3D image then this software is not for you. However, if you can see such images then Sisgen will allow you to create your own autostereograms. All you need to do is create a greyscale bitmap image with the distance encoded as brightness - the further a point is from the front the darker it should be. Many CAD packages can create such images but basic input files with simple shapes can be created easily in a bitmap editor. You then create a small bitmap to act as a sort of tile. Ths should have a fairly detailed pattern on it - I've found that close up images of tree foilage works quite well. Feed these two images into Sisgen and out pops an autostereogram which can be viewed on screen or printed. Sisgen is freeware and can be downloaded from http://www.ucl.ac.uk/~ucapwas/stereo.html I can't find much to fault with the software. It works well, produces good images and it's free. What more could you ask?
