Steampunk maker Art Donovan has just finished a whole whack of fantastic steampunk lamp designs. These are illuminating in the extreme. Link (Thanks, Art!)
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.
