Simply The Bean at Millennium Park

Cloud Gate is British artist Anish Kapoor's first public outdoor work installed in the United States.

The 110-ton elliptical sculpture is forged of a seamless series of highly polished stainless steel plates, which reflect Chicago’s famous skyline and the clouds above. A 12-foot-high arch provides a "gate" to the concave chamber beneath the sculpture, inviting visitors to touch its mirror-like surface and see their image reflected back from a variety of perspectives.

Inspired by liquid mercury, the sculpture is among the largest of its kind in the world, measuring 66-feet long by 33-feet high.

Cloud Gate sits upon the AT&T Plaza, which was made possible by a gift from AT&T.

We Chicagoans simply call it The Bean, and the primary interests among scores of us visitors at Millennium Park aren't the famous skyline or heavens above.  Rather, it's the fact that The Bean reflects ourselves in cool, captivating ways, and that's fun.  It's the fact that, unlike many art and artifacts we see in museums, The Bean is perfectly meant for touching, leaning and playing.  It was a wonderful Fourth of July holiday, not at all a crush of people and a very pleasant summer day.
