Nude Magazine's got a free, downloadable papercraft CCTV camera, for freaking out your neighbors. Put one in the bathroom. The dog house. Use it for a hood-ornament. Build Your Own Nude Magazine CCTV Camera (Thanks, Alice!)
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.
