Researchers from GRASP Lab at the University of Pennsylvania developed software to allow toy-sized nano quadrotors to fly in tight, precise and eerie formation. Gmoke sez, "William Gibson dreams of a mass of these things comprising a flying skyscraper. I imagine them as surveillance and policing drones ready to stop the OWS action or Arab Spring before it can start."
A Swarm of Nano Quadrotors (Thanks, Gmoke!)
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.
