The Equation Bookshelf is designed by Marcos Breder and is a simple idea of to divide things in priority order. As you can see the design is quite unique, stylish and original. You can put together the books that you need immediately or more important between (parentheses) or maybe a photo, or something important for you to be the focal point of this bookselhf. Set others between [square brackets] and {braces}. - Via - Designspotter
