WallFor's "We're Not Watching" CCTV wall-decals are a nice little commentary on ubiquitous surveillance. We're Not Watching (Thanks, Liam!)
Update: Liam sez, "I created the coupon code, 'BOINGBOING' to give people 10% off their orders."
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.
