One of many tricks to help people see stereograms.
- Move your face toward the screen, until you can't focus properly
on the squares. At some point, an optical illusion of a third
square should appear.
- Focus on the middle square, and slowly move away from the screen,
until you can focus on it comfortably.
- If everything has gone well, the square will appear to be on two
different levels. (You'll understand when you see it).
- Press and hold any key (or mouse button), which will make the full image appear.
Today's stereogram is of the Greek letter pi.
This was originally written back in 1998, as part of a course on cryptography and stenography.
