This is my new favorite piece of urban art -- the Chicago "bean":
Its real name is actually "Cloud Gate", but Chicagoans call it "the bean" because -- obviously -- of its shape. The 20-meter-long sculpture by British artist Anish Kapoor, installed in Millennium Park, is covered with polished stainless steel plates that reflect the city's skyline and the sky. Otherwise said: what brings the "bean" to life is the city surrounding it. Under the sculpture, a concave chamber (the "gate") multiplies your image like in a vortex.
