Litographs takes public domain (and otherwise shareable) books and turns them into word-art posters that both illustrate the text and are comprised of it. They are also doing tees and have plans for more. It's kind of cool to think of wearing an Alice in Wonderland shirt with a picture of Alice made up of the entire text of the book!
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.
