A new tumblr, Haunted Mansion Backstage, consists of rare photos of the backstage areas of the Disney parks' Haunted Mansion rides not normally visible from the "Doom Buggy" ride vehicles. For me, this stuff is the real magic -- seeing how somewhat dated robotics technology can be used to create such a wonderful, seamless illusion from the foreground.
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.
