BladesUSA offers this 14.5" "fantasy knife" that really has it all: a skull with fangs, pincers, scorpionoid body-segments, a lethal-looking stinger (perfect for inadvertent self-blinding while scratching your nose), the whole package. It comes with a wall-mounted display, though why you'd ever take it off is beyond me. (via OhGizmo)
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.
