Alien in 3D. Stare at the white line between the two pictures. Then slowly cross
your eyes til it looks like a row of three pictures. If alien in the middle
picture looks a little blurry try slowly tilting your head left or right until
it comes into focus. Another way to see in 3D is to put a finger up between
you and the computer, about 6-7 inches away from your face. Stare at your finger
as you bring it down to see the alien that was hidden behind it.
