the sky mirror in rockefeller center
I walk through Rockefeller Center twice a day most days - on my way to and on returning from work. Rockefeller Center hosts a lot of installations throughout the year. Sometimes the plaza from where this photo's eye stands is filled with television stage, art installations, rocket ships, automobiles, memorials, and Christmas trees. The alleyway seen across the sunken plaza (double duties between cafe and ice rink) is the other area where installations find themselves such as this huge Sky Mirror by Anish Kapoor and organized by Public Art Fund.
Charlie photographed and wrote in greater detail about this as well, check out his blog for this and more.
