Justin Watt sez, "the latest cover of the Princess Bride DVD has an amazing ambigram." Indeed it does -- a suitably awesome cover for one of the finest movies ever made.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
