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 Duet


The spiral wheels in Duet are pushed in the same direction when the wheel that carries them rotates in the clockwise direction. They rotate freely when the carrying wheel counter-rotates.

I find interesting patterns emerge at the tips of the spirals where I've placed the dark accents. These points remind me of a pair of dolphins playing. At times their movements are synchronized as the spirals move at the same rate in the same phase. At other times the motion is 180° out of phase and the spirals intertwine at the center of the carrying wheel.

The motion of the three upper wheels lock together as the spirals match speed and gain momentum from the carrying wheel. The spirals break free and begin their intertwining dance again as the carrying wheel begins to slow and reverse.

I have this sculpture. I bought it when I finally got a real job back in 1993 and it is the centerpiece of my family room. Everyone just loves it.
