The Book Stacking Problem

This is not the original book stacking problem, but it is still a good one. This is the book stacking that you can see in the library at the cultural centre in Handen. Locally known as Boktornet, or The Book Tower, it will surprise most visitors to the library. It was created quite a few years ago now by the scenographer Annika Thore. And if you are curious about how it was made don't ask Annika because she prefers to keep that to herself!
