Librarian.net had this tasty book link, a "house made of books." For more work by Livio De Marchi, check this out.
Been seeing this around the blogosphere the last couple of days: Monster Engine, art from kids' drawings. The Presurfer is one place I saw the link. Ditto this Literary Map of Manhattan.
Also on The Presurfer: Origami Folding Instructions, Free Online Business Card Creator, and, uh, the Chickensuit. I think I'm gonna have nightmares about the last one.
