Tower of Barad-dûr Built Out of LOTR Boxed Sets

Here's a photo from inside of a bookstore in which employees stacked a bunch of Lord of the Rings boxed sets up to create the tower of Barad-dûr. This has got to be some kind of safety hazard, it just needs one little kid to grab a box from the bottom to have the thing fall on top of him. It's still pretty rad! And if that did happen they could always sue the poor bookstore!
