moving 3D picture that I can't see

You know those 3D pictures that were popular about 10 years ago... the ones that are a bunch of colours with a random design that when you make your eyes go out of focus turn into a 3D picture? Well, I could never see them. When they had them in the comic section in the Saturday paper, I would sit for hours with the picture close up to my nose and slowly move it back, and I might have been lucky one in ten times and seen the actual thing... after trying forever. Well, apparently there are moving 3D pictures now. You will either jump up and down at how cool it is, or want to scream because you can't see a darn thing (like me).
