Samuel Mullin has a full sleeve's worth of beautifully executed Super Mario tattoos -- his site has a small gallery of them. He's doing a Zelda sleeve next for the other arm. He says he was inspired by a childhood spent in a military family, passing many days stuck in residential hotels, playing NES. Link (via Neatorama)
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.
