SuperHeroStuff's R2D2 hoodie is a $70 way to keep warm and look like a droid ($73 if you want to look like an XXL droid). I dig the way it turns into a droid-inspired fencing mask if you zip it up all the way, and the way that this makes you into something like the real R2D2 in that you have no peripheral vision and are prone to being tipped over by malefactors.
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.
