The following is a magic eye picture. Now in this puzzle there's more than meets the eye! There's a hidden 3D image in it. Now to view it follow these instructions:
Move your face close to the screen slowly then slowly move it back, but don't focus on the screen. Imagine there is no screen and your looking at something behind the monitor. It might not come at first but practice makes perfect! I don't know if it works using 3D glasses but you can try.....i doubt it though. Sooner or later you should notice the picture coming into focus automatically. But whatever you do! Don't try to focus it yourself or you'll lose the picture!
