A Study in Chaos is (was?) a temporary kintetic installation running from February 3 to April 27 of 2020. It is (was?) located in a vitrine on the north side of Thomas between Boren and Terry in South Lake Union, Seattle.
It consists of 111 fidget spinners, each with a magnet mounted in each of its three arms. Mounted in a hexgonal tiling, these magnets are free to interact with each other, causing ripples of motion to chaotically move back and forth across the panels. This video provided the original inspiration.
