This might be a bit hard for some, but I thought it was sort of neat. Not done yet, and it doesn't work real well so far, but you can actually see a bit of 3D to it. It's called a stereoscopic picture.
You have to cross your eyes a bit to look at it. Treat it sort of like one of those 'Magic Eye' pictures. You want to cross your eyes enough that you see three images. Try to focus on the one in the middle. Good luck :P
