Joyous Jumpers in Chicago

CHICAGO — The Bean, whose formal name is Cloud Gate, is one of the most joy-producing attractions in Chicago. It is a massive work of art (33 feet wide, 66 feet tall and 42 feet high) built with 168 stainless steel panels, each weighing one to two tons. Its lower portions are within reach, and cleaning crews wipe off fingerprints twice a day. (Photo by Tom Adkinson)
