Kumi Yamashita's "Constellation" series are portraits made from a continuous piece of black thread, strung around and around a dense mesh of nails hammered into a white-painted wooden board. Shown here: "Erik".
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.
