In 2011, a Japanese artist Fujiko Nakaya created a surreal installation that allows members of the public to feel like they are walking on clouds. Of course, the fog – it’s more of a conversation with nature, while the clouds ever – something romantic. The installation, which is entitled ‘Cloud Parking,’ is created using a specially made system of pumps and fog nozzles. These clouds are located in Linz (Austria), on the roofs of houses. According to visitors – it is great fun to disappear there, and appear in another place of the fog.
