Remember the 1990s craze of Magic Eye posters? Just like those, the spectacular space pictures in this gallery can be brought to life in 3D when viewers use a trick of the eye – with no need for special glasses. Stare into the screen and allow your eyes to defocus. You will get double vision as each eye sees the L & R images separately. Move your head towards and away from the screen until the two middle images overlap. The single overlapping image should be in 3D.
I can never get these things to work.

Now THAT is cool. I have too many eyes to make it work properly, but if I hold them just so, it does work.
I used to love those magic mirror pictures that you had to gaze at for 2 minutes before you could see the hidden image. After I had lazik surgery, I can no longer see them correctly. It's like I can only see the negative effect. Weird.
