In the garden courtyard of ASM International, a society for material engineers and scientists, stands a prominent water feature composed of two independent sculptural elements. The taller structure stands 16 ft. from the base and is made of copper. The shorter, curved arc is made of titanium and stands 14 ft. tall. Stainless steel rings fitted around the perimeter of the feature's base create small streams of water that fall over and around the top pool into the lower pools.
