I wanted to explain this neat object near the Chicago Art Institute. I found the explanation for it online and here it is for you who have never been to Chicago...

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 the city'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 had fun watching people walking around inside and out, I could have stood there watching for hours.
