The kinetic sculpture, Silver Rain, located above the escalator was designed by Tim Prentice of West Cornwall, Connecticut in 2001. The composition is in the shape of a cylinder and is made up of 420 identical kinetic elements of reflective aluminum. The sculpture is 20 feet in height and 15 feet in diameter. The individual reflectors are designed to move with the slightest air currents and are organized into seven groups, which can revolve independently of each other.
