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 Geppetto


Geppetto is a nostalgic piece. I’ve combined the patterning wheel and mechanism concept from a 1986 sculpture called Puppeteer with what I’ve learned in the ensuing 14 years. The resultant new sculpture is larger, runs longer and I think looks better but still has the strong optical patterning effect of the older design.

The “arms” at the top of the sculpture are counter-weighted by long “legs” that frame the left side of the piece. The arms pull on strings that cause the patterning wheels to rotate in opposite directions. This creates a strong moiré effect that appears to grow and shrink.
