Breokz uploaded a photo of "Xmas at the lab of Avans University of Applied Science." Chemistry may all be "pretty colors and things that go bang," but it sure makes for a festive tree.
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.
