If you are a bibliophile like I am, have read all your books, like seeing them, but hate lending them out (they never do seem to make it back home, do they?) then why not try this?: Remove all the dust jackets from your non-collectible hardbacks (don't worry, you can store the jackets for later if you get book-rapist remorse), and stack them according to size and color. It's unexpected, less cluttered-looking, fresh, and just publicly OCD enough that new friends to your house will be slightly afraid of you. Which is never a bad thing, no?
