About This Portfolio

This is a listing of all the kinetic sculptures I have created since 1975. It is an archive of historical and current work. Most of these are no longer available for purchase because they were created in limited editions. Go to the Current Works page to see sculptures still available for purchase.

You will find photographs, possibly videos, and much more information on many of the sculptures by clicking on the "Click to read more..." link. I have limited information on many of the sculptures from the early years. They were created before video cameras!

About Harmony 

I think of Harmony as a vertical mobile. It is a sculpture of balanced layers that interact with each other. The main carrier arm is pushed clockwise for a short interval by the drive mechanism. This action starts the entire upper assembly motion which continues rotating clockwise until it runs out of energy. The main carrier arm then falls back, triggering the mechanism and starting the action all over again. The motion appears random. It depends on the relative speeds of the two carrier arms when the drive impulse occurs. 

I started working on Harmony in an attempt to make a smaller version of my larger sculpture Gemini. As I played with the drawings and animations it morphed from a 2-bird piece into the current form.The bird forms are the same but the action is quite different.
