"Überwachungsstaat - Was ist das?" is a short animation narrated in German (with English subtitles) that does a very good job of explaining the evils of mass surveillance. Being German, the narrator is allowed to make comparisons to the Nazis without invoking Godwin's Law, which turns out to be surprisingly useful.
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.
