Tackyshack's "The Portal is a Lie?" is a beautiful trick "painting with light" photo -- a camera is set with its shutter open in a dark place, and small lights are used selectively to illuminate parts of the image, and to draw shapes in space. The photo simulates a person going through a portal from the game of the same name, and it's a rather ingenious use of the technique.
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.
