Comrades, I present to you the unheralded but noble sport of "anvil launching" in which a brave athlete puts a crapload of black powder between two anvils, lights a fuse and runs like the devil, then watches as the topmost anvil sails hundreds of feet into the air!
Gay Wilkinson is the world champion anvil launcher and in this brief video, he demonstrates his grace and athleticism and total disregard for commonsense or safety. Gay, you are a credit to the sport.

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.
