Nouvel in the Institut du Monde Arabe draws motifs from Arabic architecture – the mashrabiyya, to generate a paatterened patter that is rather revolutionary in concept. He drew inspiration from the traditional lattice work that has been used for centuries in the Middle East to protect the occupants from the sun and provide privacy. The system incorporates several hundred light sensitive diaphragms that regulate the amount of light that is allowed to enter the building. During the various phases of the lens, a shifting geometric pattern would be formed and showcased as both light and void. Squares, circles, and octagonal shapes are produced as a result of the reaction to the sunlight coming through the system. Interior spaces are dramatically modified, along with the exterior appearance. While these ocular devices create an incredible aesthetic, they fail to work properly and they have been considered to be one of Nouvel's failed attempts. I however find it a quality projict that needs technical revaluation..
