Flickr user Tinkerbots creates and photographs beautiful raygun and robot assemblage sculptures made from techno-junk. I am SUCH a sucker for raygun sculptures. Tinkerbots's blasters drive a fishhook straight into my desiderata gland.
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.
