Matt sez, "The guy behind one of my favorite web comics, Dr McNinja, did this awesome tshirt design wherein Mario's world is de-cartooned and amped up. Yoshi is a scary dinosaur with a monstrous tongue, goombas look like acid visions of mushrooms and the piranha plants have shark-like teeth."
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.
