A Museum With Wings
"Brise soleil," in terms of architecture refers to a variety of permanent structures that protect you from the sun. This mechanism looks like a wing and was designed by Spanish architect Santiago Calatrava for the Milwaukee Museum of Art in Wisconsin, USA. His two ultrasonic wind sensors make the wings close automatically if the wind's speed reaches 37km/hour or more. The wings are also folded and then released two times a day, which takes a total of three and a half minutes.
