This site sells giant, standing sans-serif letters with bookshelves hidden behind them -- you can spell out freestanding words and store your books around back. These remind me of the giant words painted on the walls of the Kotters' apartment in Welcome Back, Kotter.

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.
