Zephyr is the first freestanding sculpture I've designed and produced in several years. It's always a challenge to get "off the wall" and design something that can be viewed from all angles.
The drive mechanism and motion of this sculpture are quite simple. The arms move up and down in opposite directions. They pull on strings attached to the common axle of the upper spoked wheels. These wheels turn together several revolutions in one direction and then reverse. The basic mechanism is quite simple but the patterning created by looking through the double wheels is complex and variable. It changes with each shift in angle you view the sculpture from.

Animated gif-formatted drawings work well when using Netscape Navigator 3, Microsoft Explorer 3 or more recent versions of these browsers. The gif animation will repeat itself and play more rapidly when the page has finished loading. It takes 1-2 minutes for all the frames of the animation to load. This type of animation is very compact and works well over the Internet but it has it's limitations. The speed that the animation plays back at depends on the viewing application that you are using and the speed of your computer. In order to keep load times short I have only used enough frames to give a brief idea of the motion. This should only be considered a brief sketch of the motion.
