These images have a hidden message. Only those that know how to see it will be able to reveal the 3D-effect. It is recommended to look at the pieces in their original size or slightly bigger (100 % - 150 %).

How to see the hidden message: If you wear glasses, try with and without them. Some short-sighted people see the images easier without glasses.

Position your face so your nose is almost touching the picture (or screen). The picture is out of focus (blurry), because it's too close. Now, pretend that you are looking straight ahead, right through it, then slowly move your face away while keeping your eyes pointed straight ahead. The hidden message should appear when the picture is at the correct distance.
