For 60 Euros (and up), avant-gardge Viennese artist Evelyn Fürlinger will hand-crochet you a custom laptop sleeve with a design of your choosing: I'm especially fond of the red go-faster stripes.

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.
