Seen at New York Comic-Con, which I'm presently attending: Yaya Han's hand-cut foam cosplay wings, which come in a variety of styles, including devil, fairy, angel, cherub and steampunk. They're darned cute, and I bought a set of batwing devil versions for my daughter.

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.
