Book tree - functional art! ... cool feature wall for the library/ study/ storage room just off our main entrance - could see this feature wall through the double glass doors ... maybe attach or embed miniature lights along the wood branches so would twinkle the tree shape at night :)

Line: The book shelf in the room shows the use of line because the book shelf shelves are built against the wall forming a miniature tree. Our eyes are drawn to look at the book shelf tree from bottom to top and outward to the tree/bookshelf branches.
