In 2009, Juliana Santacruz Herrera began filling Paris's potholes with elaborate knitted plugs; she called it "Projet Nid de Poule" (Project Pothole). What the yarn lacks in durability it makes up for in whimsy.
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.
