Thats a really tall library...
I think it's a cathedral with a library inside
First it was supposed to be an underground-library. Well, it's still. But now bigger and less cave-like like I first had intended.
[Edit]
Imagine you go back to the 14th century. And you give the people an Eggs Box 3.60£ and some random ego-shooter.
Will they be like "Oooooh, aaaah!", totally amazed?
...or will you return with a pitchfork in your back?
