To see a three-dimensional stereo image, look at the double image of the discus thrower above these lines, and cross your eyes slightly until the two images blend into one. (Wait until you see three images, one in the middle and two fuzzier ones on the sides; then, focus on the middle image.)
Don't do this too often, or you may get a headache! No, I am not thinking of getting seriously into stereo imaging. This is only for fun ... at least for now!
If you could not "see" the previous image in stereo, you may want to try this one. Instead of crossing your eyes, it requires you to be wide-eyed (or "pie-eyed"). To see the three-dimensional stereo image, look at the double image of the discus thrower, but pretend that there is a 200-meter long battleship "parked" right in front of you, and that you are trying to see the entire battleship, from tip to tail, at the same time. (Wait until you see three images of the discus thrower, one in the middle and two fuzzier ones on the sides; then, focus on the middle image.)
