3D printing has come to Sears in the form of this $1800 computer-controlled Craftsman CNC machine that can "print" your 3D designs on wood and other materials, either from a direct PC hookup or a memory card.

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.
