Wuffabet is a new Android app for small kids: an ABC book with great illustrations and music and really cute animations (it also has some very good nonstandard animal choices, like U for Urchin (sea urchins), F for Flying Squirrel, N for Narwhal, O for Octopus, and Y for Yaffle!). It was created by Chad Essley, who's done animations for Sesame Street. A nice option for post-present-opening lulls and new phones/tablets.
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.
