The ultimate ray gun pen
An absolutely gorgeous ray gun pen by the appropriately named ACME Writing Tools, available mid-February for $130. The barrel separates from the brightly colored, Marvin Martian base as a retractable roller ball. I only wish the handle / stand were less cartoonishly abstract.
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.
