Dots
If you can cross your eyes, look at the two pictures and cross your eyes until there are only 3 images, then you should see the pic in 3D. This is the inverse of magic eye pictures, because I find it a lot easier to do. Soon this page will be updated so you can choose from a number of pictures and choose which way round you want the pics - i.e. so you can see them in 'normal' magic eye mode.
