Japanese architecture firm Tetsuo Kondo Architects in collaboration with environmental engineering firm Transsolar have created an installation called Cloudscapes, located in the Sunken Garden of the Museum of Contemporary Art Tokyo. Cloudscapes gives visitors the experience of walking up a staircase, through a cloud. As the project states: ‘The temperature and humidity inside the container are controlled to keep the clouds at their designed height. The air inside the container forms three distinct strata, one cool and dry, at the bottom, a warm and humid middle stratum, and a hot and dry stratum at the top. The warm, humid layer is where the clouds form.’ (Via)
