Have you ever tossed a handful of pebbles into a sunlit pond and caught an eyeful of sparkling reflections? Here, 170,000 hanging pins create rippling reflections. Turn the knob to set them in motion. As the pins dance, each pinhead acts like a tiny mirror, reflecting the nearby colored lights to your eyes. In some places, the vibrations build, creating sinuous, rolling waves. In other places, the pins interact to minimize movement, creating relaxed areas that are peaceful and calm. In the center, five squares of different-sized pins make a pattern of their own.
