Craftster's Teriyakimoto knitted this (non-functional) gas-mask hat for work and play (e.g., "Hey, honey, let's play stern-but-soft air-raid warden and recalcitrant claustrophobe!"). Teriyakimoto plans on using it as a bicycling hat during the long winter months. Link (via Craft)
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.
