Digital Water Pavilion by MIT

Massachusetts Institute of Technology researchers design a building made of water that will flow at Expo Zaragoza in Spain next year. The walls will be made by water and operating digitally. This water curtains can show shapes and it also can open gate for visitors. The roof will be supported by large pillars that can move up and down. When there is too much wind, the roof will lower. Similarly, when the pavilion is closed, the whole roof will collapse to the ground and the structure will disappear. {via}
