Maybe it would help to post a normal stereogram? (this one is of a shark)



Anyway, a stereogram is an optical illusion that makes a 2D image appear 3D. If you can't see the 3D illusion, you'll never be able to tell what the picture is of, whereas if you can see it, it will be obvious. Incidentally, the image is of a smiley face:

To see them, you don't just stare at them, you have to assume a certain amount of control over your eyes. If you're nearsighted, it works better if you're not using glasses or contacts. You know how if you're not focusing on something near your eyes, it will sort of look like there are two of them? Touch your nose with your finger, and slowly move it away. If you focus on your finger, you only see one finger, but if you look past it, it splits into two. Anyway, you need to be able to control your eyes so that you can precisely move those two images apart and back together slowly.

Now, a stereogram consists of a repeating pattern. Find a point that repeats, like the black vertical stripe on the shark picture or the "Q" in my text stereogram. Now, use your eyes to split the image in two, and get that point to line up with the next matching point in the repeating pattern. Once they line up, just hold that for a few seconds, and you should be able to see a 3D effect.

If this isn't working, say where I'm losing you.
