Kinetic Sculpture, Switzerland by Willi Gutmann

A column of thin metal leaves twists like a dancer caught mid-spin.

This kinetic sculpture is from Switzerland, contemporary, in aluminum and steel, by Willi Gutmann (1927-2013). Gutmann was a Swiss sculptor known for clean metal forms, many designed to move, turn or be rearranged so that the work changes with each handling. Dozens of stacked aluminum plates pivot on a central steel rod, fanned into a double spiral that swells and narrows along its height. A small flat cap and needle finish the top. The rod rises from a plain cylindrical base. It is 16.25 inches high and 1.63 in diameter.

Give it a turn and it rewrites itself.
