You remember those, right? A few pages of Magic Eye and I found my eyeballs crossing of their own volition. (Now all I have to do to get the same effect if sit in front of a computer for a few hours straight. Fine detail, argh!) Anyway, these works by Robert Bruce Murray III of Sort of Natural had me staring for quite a while. If only to try to figure out what's going on. There's a story in there.
