Randall Munroe has finally finished Time, his 3,000+ frame slow-motion animation that began life as wordless, enigmatic single-panel XKCD installment. Since then, the panel has been slowly, slowly updating itself, running out its course over several months. Geekwagon has collected the whole series in an easy-to-control window, and the story, taken as a whole, is a beautiful and odd existentialist parable touching on the discovery of geographic knowledge; cultural first contacts; environmental disaster, friendship and ingenuity. (Thanks, @dexitroboper!)
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.
