Tate Modern’s new large installation has visitors gawking. “Nothing prepares you for the almost psychotropic transformation of human social behaviour that is currently taking place where the turbines of Bankside power station once roared. Olafur Eliasson’s The Weather Project only opened a couple of weeks ago, but it is already a legend. Visitors seem to think they are at some storied 60s festival – barriers are melting, frosty politeness traded at the door for cockeyed mysticism and love, love, love. Under a vast blazing sun, in clouds of dry ice, revellers lie, looking up at what must surely be the biggest mirrored ceiling in the world, and conclude that, hey, maybe we really are all made of stars. The scale is so excessive, it is hard to experience Eliasson’s artwork as art – it is more like nature itself, and we, down below, make the art.”
