As part of the Arteplage Yverdon-les-Bains for Swiss EXPO 02, a group of architects called team extasia have designed a building made out of fog.

The building is a media pavilion on Lake Neuchatel in Yverdon-les-Bains, Switzerland. The building itself is created from filtered lake water shot through 13,000 fog nozzles.

Visitors will approach via a 400 foot long ramp. Each visitor will answer a questionnaire/profile and receive a 'braincoat.' The coat protects visitors from the damp environment, but it also changes color depending on whether nearby people are compatible (red) or incompatible (green).
