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 North Star


My first sculptures in 1975-76 ran for about 20-30 minutes, I considered them a success but I wasn't satisfied. I've spent the past 35 years exploring new designs, mechanisms and building techniques and one consideration is always run time. Runtime grew in leaps from less than half an hour to 1 hour then 3 hours then 10 hours. Last year I was pleased to introduce my first single spring sculpture than ran for 24 hours, White Water.

This year I'm introducing North Star, my first sculpture that runs for 40 to 50 hours. A long runtime wasn't the goal of this sculpture but the result of the type of patterning I was trying to create. I'm using two similar but different wheels rotating in the same direction at different speeds. For the patterns to emerge properly the wheels have to rotate very slowly. The side effect to the constantly changing patterning is a very long runtime.
