Dark Roasted Blend has a fantastic roundup of junkbots and other robotic ephemera and goodies. I'm really taken with Ultrajunk's creations, which really take advantage of the decay and use-marks on his found-object materials to make robots that have a lot of texture and implied history.
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.
