Jean Nouvels “Institute de Monde Arabe” in paris. Visibility and ambience controlled by actuators. These diaphragms operate like a camera lens to control the sun’s penetration into the interior of the building. The changes to the irises are dramatically revealed internally while externally a subtle density pattern can be observed.
