BoingBoing is giving a free HP Envy laptop to the writer of the best literary mashup, and the 100+ entries so far include a mash-up of Star Trek and Dickens' A Christmas Carol. Plus A Clockwork Orange with zombies. And Edgar Allan Poe's Hamlet. The best, though, might well be Thoreau's Walden as reinterpreted by H.P. Lovecraft. Hell yes. [BoingBoing via L.A. Times]
