Update: Greg adds, "Erik did not do the music–that’s Creative Commons work downloaded by Terran McCanna, who did the animation and additional website artwork and graphics. Astrid helped with research and photography. Alexandra is blogging as Hope Hodgson, and we invite contributions of artwork and dreams of the far future. Erik did a Flickr photolog which we’re also using on Moo cards we’re handing around at Worldcon. Plus buttons, of course."
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.
