Darren Barefoot sends us this link to a timelapse video of a MakerBot 3D printer extruding a copy of Stephen Colbert's head, noting, "John Biehler has a 3-D printer, an excellent photographic eye and whimsy."
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.
