ZOMG ZOMG ZOMG. Nipper, a Counterstrike map-hacker, has devised an incredibly detailed reproduction of the Haunted Mansion at Walt Disney World, a ride so fine I wrote a novel about it. Nipper's packed a jaw-dropping amount of detail into the map, even down to various behind-the-scenes sections, and has creatively improved some of the slacker moments in the ride, such as a set of Eschereqsue staircases to one side of the otherwise boring stair-climb. The only thing that could make this better would be modelling ALL the backstage areas, so you could tear through the break rooms and maintenance areas with your giant guns, hunting your fellow players.

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.
