A stereogram is one of those goofy looking pictures that you stare at until you see a 3d image.

If you are using at least 256 colors and 640x480 resolution these will work.

Remember, stare at the whole picture, you can't focus on any given point.

If you are only running 640x480 go to "Options" and uncheck all of the "show" options to get a larger viewing area.

I don't have a clue as to how these will work if you have a flickering monitor.
