Cool Christmas Tree

Christmas Tree made of books. I took this photo at the University library last year and was sure to tell one of the librarians how good an idea this was. As far as I remember the books were old reference books that weren't used much anymore - they are bound to be available online
Keep in mind that this was just a picture i took at the locval University Library in Aalborg - www.aub.aau.dk/ - thanks for the nice comments and making this a fave.
