Usually traditional bookcases have a rectangular shape, so a simplistic, static design and their main goal is to store as many books as it is possible. If you need to create a dynamic and modern atmosphere in your room, then you can add these twisted tower bookcases.
Joel Escalone, the designer of these bookcases called them MYDNA bookcases. The fact that they are twisted makes them resemble a strand of DNA or an infinite column. The twisted shape creates the idea of dynamism so that you have the feeling that they move continuously. They are twisted, but beautiful.
