Please do not pay any attention to the horizontal structure behind the diagonal buildings. Look at the building with the plants growing out of the walls... Thats is a green wall. This is a wall next to the Musee du quai Branly, a museum dedicated to ancient native artifacts of the world but based on the French perspective of what the world is.
This wall flips the reality vision that we have on mother nature. Plants grow vertically... This organic facade flips the eye and grow horizontally.
