Just cross your eyes and a third image will appear in the middle. It takes a tiny amount of concentration but the middle image will become clear and look 3d and everything else will blurry.
You remember the game kids play where they touch their fingers together and cross their eyes and it looks like a sausage finger appears inbetween the two?
or we could just look at the single image.
