Kinetic sculpture recreates grass in the wind

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.
The show is happening at Truck Gallery in Calgary, Alberta, Canada, it opens on June 3rd, and runs till the 30th."
