Carlos sez, "Here´s the handmade felt artwork my girlfriend produced to customize a regular t-shirt. There´s a couple more details on her flickr. It´s her second Mario customization for T-Shirts. She also produced a perfectly proportioned 1Up Mushroom. Both T-Shirts are mine, and I´m glad." Blue Shell T-Shirt (Thanks, Carlos!)
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.
