Amazing Book: Codex Seraphinianus
I think I have found the strangest book ever published. It's called CODEX SERAPHINIANUS by LUIGI SERAFINI. It appears to be an illustrated description of another world, written in an unknown language. I find it very inspiring, a work of mad genius. Please see some pictures from the book on the web:
I heard about it in Hofstadter's Metamagical Themas, which was great.
The Codex might be available in large libraries. Carleton had a copy. It's a very rare book, just about impossible to buy, oversized, printed on beautiful paper, and full of color illustrations. If you have the heart of an artist, I highly recommend you check it out.
