There are three sets of water sculptures in the main atrium. They are made of curved copper with a bronze patina finish. The sizes range from 42 feet to 52 feet tall and are 30 inches wide. The vertical curve of the copper is sinusoidal and the curves alternate from top to bottom. The water magically disappears above the glazed aluminum curtain windows and continues beneath the window. The ridged surface slows the water so that the water's inherent surface adhesion causes it to cling to the copper surface.
