Thanks to Kiam who sent me the link to this.
Chris Cobb, an artist from San Francisco did something amazing. He arranged every single one of the 20,000 books in bookshop, Adiobe Books by color. The project is called "There is Nothing Wrong in This Whole Wide World" and is based on Cobb's idea:
"Even though there is so much to be unhappy about in this world, we should try to create something amazing and beautiful and interesting despite all of the problems." Chris Cobb
Cobb had 16 volunteers and they spent 10 hours arranging all of the books by hand. Inside every book there is a tag saying where it belongs.
This Installation has recieved a TON of attention, literally hundreds of people have visited the book store, including entire classes from local schools. I'm so jealous. I want to go to San Fran to see itttttt.
