Zhanna, a cake-shop in St. Petersburg, Russia, creates incredible sculptural cakes in the form of government documents, newspapers with herring on them, card-tables, casino games, maps, eye charts, skyscrapers, tennis shoes... Link (Thanks, Anonymous person!)
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.
