David Bynoe sez, "This is a kinetic sculpture I built to look like a field of wheat blowing in the wind. It consists of 40 wooden poles, each about 6' high that are hooked up via a series of ropes to a pair of large motorized cams. Each cam turns at a slightly different speed, and the movement of each is mixed so that it will take about 14 minutes for the machine to repeat its pattern.
