This artwork consists of 200,000 stainless steel one-inch disks mounted on a lattice panel attached to the wall of the 55-foot circular staircase/escalator opening between the BART and AirTrain stations. The wind and the movement of the trains cause the disks to shimmer and to create a mesmerizing image of the wind.
