Wind Leaves

Wind Leaves is a public artwork by American artist Ned Kahn located on the downtown lakefront Pier Wisconsin in Milwaukee, Wisconsin, United States. It was created in 2006 and consists of a series of seven 30 ft tall structures made from aluminum and stainless steel. The structures, which move with the wind, have leaf forms at the top covered by thousands of stainless steel disks.

The seven 30 ft . structures that make up Wind Leaves each have a semi-circular form at the top which is covered by stainless steel disks. This provides a sparkling surface that reflects its surroundings such as the lakefront, city traffic at night, and the sunset. There are hand wheels on the support columns that allow the viewers to interact with the sculpture by turning it. Wind Leaves also has ball bearings in the columns that cause the work to move with the wind. The artwork has a musical component as well. There are a group of benches with drum sticks around the columns that can be played like xylophones, and there is a musical instrument that can be played by dropping pebbles into it.
