Some ideas are just too easy, too savvy, too budget-friendly to NOT share.  Sure it might take a little bit of time and a healthy dose of patience, but if you've got a few bookshelves and a whole lot of books, try pulling them out and organizing them by spine color to give a drab room a sparkling makeover of pure eye-candy.  It's the perfect project for a grey wintry day.
