A building made of water: sensing and actuating architecture

As architect Carlo Ratti tells in his TED talk on 'Architecture that senses and responds' the physical world turned into a digital one during the last decade, but now the digital world is turning again into the physical one, as the omnipresent digital data can be used to create our physical environment. Many examples can be found on the website of his MIT SENSEable City Lab and in the TED talk.

One of the most beautiful examples of sensing and actuating architecture is the Digital Water Pavilion, built in Zaragoza. It really is a building made of water. How it works is shown in the TED talk. Wonderful to see how it even can disappear!
