Cloud Gate--referred to by locals as The Bean for obvious reasons--is a public sculpture by talented British artist Anish Kapoor. Cloud Gate weighs in at over 110 tons, and is 66 feet long and 33 feet high. The Bean was created using a huge number of individual stainless steel plates. Cloud Gate's seamless surface is the result of thousands of hours of polishing. The sculpture has the appearance of a giant drop of liquid mercury, and the mirrored surface offers an amazing reflection of the city's skyline, even more breathtaking on a bright, clear day.
