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!

Spectrum Kinetic Sculpture Directions 

About Spectrum


I've been designing and building kinetic sculptures for the past 30 years. During that time I've found inspiration from a number of different sources but one that has stood out is the kaleidoscope. The continually shifting forms fascinate me. (The colors are nice but I'm more excited by forms!) I've built a number of sculptures that create striking patterns and most of them shift through at least 2 phases, but none have been able to replicate the variety of forms shown by a kaleidoscope. Spectrum is my first sculpture that begins to give me the true "kaleidoscope" feel.

I built Spectrum using 4 matching patterning wheels. The two outside wheels move at the same speed but in opposite directions. They reverse direction after about 2 revolutions. The center wheels move in opposite directions but at varying speeds. The net effect is a continually changing set of patterns that become quite dramatic at the point the outside wheels change direction. 

I found that the wheels had to move quite slowly for the patterns to develop. This necessitated some study and the redesign of my basic "2 arm" mechanism. I was somewhat surprised and quite pleased that this also resulted in an extended run time of more than12 hours. Thirty years and I'm still learning!
