Alexander Lervik's MyBrain lamp is modeled on his own brain, as run off a 3D printer. In the coming era of mass-customization, we won't have to settle for lamps based on their designers' brains -- we can each of us get lamps based on our own brains. Link (Thanks, Laura!)
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.
