As mentioned before, I'm a big fan of the beautiful handmade shoes from Cydwoq, who manufacture their wares to order in Los Angeles. Here's a short and beautiful documentary on their factory and manufacturing techniques.

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.
