On March 25, Randall Munroe ran a strip called Time, an enigmatic, wordless image whose tool-tip was "Wait for it." Ever since, the strip has been updating with subsequent frames, all of them making up a time-lapse animation of a lovely story about a day of sand-castle building at the beach.
The XKCD Wikia entry for the post has animated GIFs and a slideshow showing the progress to date. It's really coming along nicely, and Randall's done some clever things with the back-end to stop people from previewing future frames.
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.
