Have a look at these 10 pictures, and see if you can see the spectacular 3D images hidden in them.
If you cannot see the images, do not desperate. Keep looking and trying to make slight changes to the focus of your eyes, until the images are suddenly revealed in front of your eyes.
The first one is the difficult one. After you find out how it is done, then it is fairly easy to reveal the other images too.
Good luck.
Really cool stuff.
