Avi sez, "Paper Commander offers free downloadable pdfs of plans for paper models of cool spaceships from the Wing Commander universe. My favorite is the F-109 Vampire."
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.
