Some folks set up a digital projector outfitted with an FM transmitter and put it inside a car. Every couple of weeks they send out an e-mail to a listserv full of fans with details on the movie that will be showing, the wall it will be projected on, the time and whatnot. You show up, tune to the designated FM station and enjoy a flick, or steam up the windows. The Mobile Movie movement started in Santa Cruz, and is now playing in Berkeley, Oakland, Minneapolis, Dallas, Los Angeles, West Chester, PA., and Tampa City, FL.Link
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.
