Kindle
Here's a great project for those giant, awful hardcover books you find at library sales: convert them into wall-mounted bookshelves.

Update: Here's the inspiration for this
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.
