This is the most amazing, thought-provoking library I've ever seen. Jay Walker's Library of the Human Imagination. Note: This is a private library, so I will probably never be able to see it in person, but a girl can dream :)
Okay, I added the words on this last one, but it's an appropriate sentiment :)
You can find an amazing walk-through video of the library here: The Walker Library of the Human Imagination. It is totally worth the time to view. Really a beautiful, inspiring visual paeon to human knowledge.
