Ugo Rondinone's "Cry Me a River"
I've visited Ugo Rondinone's exhibition "Cry me a River" and I really like it. It's worth waiting until the other people in the exhibition move on to the next room. When you are completely alone with the artwork, you can simply sit on the floor and escape the constant sensory overload of everyday life. I particularly liked the room full of children's drawings of the sun.
