Mike,
I used to really love admiring these things. I mentioned that you might find some examples in old issues of Discovery Magazine. Also, you can find a few in Hofstadter's old columns in Sci Am titled "Metamagical Themas" (an anagram of his predecessor, Martin Gardner's column "Mathematical Games"). Also DH had a few books, "Goedel, Escher, Bach," for example, that has some, IIRC. This one also contains other kinds of related ideas. I actually read it, but I think it would be nice to browse as a coffee table book.
