I'm heartily impressed with this elaborate steampunk remake of several Iron Man action figures from Sillof's Workshop, home of many fine steampunk action figure mods. The bulletproof "prototype" suit (not pictured here) is especially tasty. Link (via Gizmodo)
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.
