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 Variation Jazz


Variation-Jazz is the 7th in the Variation series. I find this series to be a fascinating exploration. In this case I started with the ellipse shape and looked for a way to balance it that created interesting patterns. It took many iterations before I was satisfied.

This process is much less painful today than in the "old days". I begin by drawing my initial idea in Adobe Illustrator (an object oriented drawing program). I link this drawing to a file in Adobe After Effects (a special effects animation program). In After Effects I can tell the sculpture parts how I want them to move relative to one another and preview the resultant patterns. This set up then enables me to quickly move back and forth between programs, tweaking the drawing in Illustrator and observing the new patterns in After Effects.

This procedure is much faster and more interactive than the old system of drawing the parts, quickly cutting them out of some inexpensive wood, assembling the rough idea, testing it and then going back to the drawing board to start all over again!

David created our first Variation Jazz and we loved it so much he kindly produced a mirror image for an opposite wall. The two sculptures have entertained and enthralled patients in our practice waiting room. No one wants to wait for long but when they do, we are sure that the gently moving sculptures make waiting far more interesting and children and adults alike find them fascinating. Thank you for the ingenuity of your moving artforms.

David rarely does custom work but he did make a reverse Variation Jazz for Dr. Crouch. Working on an opposite takes some concentration! Would love to visit this waiting room in the UK someday. Thanks for visiting and commenting. Marji
