Located on Lake Neuchatel in Yverdon-les-Bains, Switzerland, the Blur Building was designed by Diller & Scofidio for the Swiss Expo of 2000. Regarded as 'structure which blends into its surroundings', the Blur building is made by spraying tiny drops of lake water from 31500 jets that adjust to changing weather conditions to create the same blur effect in all seasons. The inside space is as amorphous as the outside walls. This weird structure can hold 400 visitors at a time.
