The new Musée des Confluences in Lyon was opened to the public, in late 2014. It was created by Wolf D. Prix of the Coop Himmelb(l)au team, which was founded in the 1970s. Many avant-garde groups from those wild years – such as Archigram, Superstudio, Archizoom, Haus-Rucker-Co, and the Japanese Metabolists – are now consigned to the past, but the Coop Himmelb(l)au architecture firm, whose special aspiration was always to bring into the world buildings that overcome the pull of the earth – buildings "to float on the horizon like clouds" – is more in demand than ever.
