Tomás Saraceno: Cloud City (Ville Nuage) Cloud City refers to how it feels to float in the air, condensing the gap between our perception and experience of the ocean of air at the bottom of which we dwell. When it comes to buoyancy – the tendency or capacity to remain afloat in a liquid or rise in air or gas – or more precisely to experience buoyancy the sensible dimension seems to override the scientific thermodynamical and physical explanations or implications. This exhibition took place in Belfort in 2012.
