Cloude Gade is one of the most famous sights of Chicago. This scoulpture is popular with tourists as a photo-taking opportunity for its unique reflective properties. The sculpture challenges perception by distorting and deforming the surrounding architecture. As for me, Cloude Gate looks like a time loop, which unites time, space and people. I saw the "The Bean" lots of times and I was always wondered why people used it only like a curved mirror. In fact, this object is the symbol of the boundaries of human.
