这是一个很有趣的书架，用它来平衡你获取的知识。在这个书架的两边可放不同种类的书籍，如：左边放经济类的书籍，而右边放漫画类的书籍。
其中有一边的书多过另一边它就会压下去而另一边就会翘起来，提醒你应该要少看少买漫画书了。而下面两个类似秤砣的木框可在里面放置花瓶或相框等东西，而且也可以左右移动，当然它也有用处，如果你希望哪一边的书籍多一点可加重物品或移动方向。设计师：Denis Oh。
译文:
Maintain The Balance of Your Knowledge
This is a magic bookshelf that can help to balance your knowledge. Put on each end of the shelf different books, for example, books on economy on the left and cartons on the right.
The end on which more books are assembling will be bending downward with the other one warping upward, reminding the owner to stop buying cartons. The two removable wooden frames, in which vases and picture frames are placed, play the role of weights. Put more things in the frame or adjust directions if you want to have more books on one end.
