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!

Labyrinth Kinetic Sculpture Directions Edition 1-24
Labyrinth Kinetic Sculpture Directions Edition 25+

Note- David made a slight change in the Labyrinth mechanism between #24 and #25 which adds ease in construction. The visual image is different so David updated the instructions to match. Installation and operation is the same in both.


Labyrinth mounted on the wall in a contemporary room setting.

About Labyrinth:


Labyrinth is an easy-to-live with kinetic sculpture that meanders along unfolding a variety of hidden patterns while making soft, wooden clicking sounds.

This sculpture had a difficult birth. I designed the patterning wheels in 2007 but it took five years before I perfected a mechanism that moves them appropriately. One of the fine points I strive to achieve is the optimal pacing of the wheels as they move in either opposing or matching directions. The power mechanism has to be designed and tuned to deliver that exact rhythm.

To complicate matters, I love simplicity and efficiency and fuss to maximize run time while minimizing power input. I am able to power the wheels in Labyrinth with just a single spring and still get about 7.5 hours of runtime. The key is in the five balls providing a visual interest factor in the background. Yes, they are necessary! Visit the blog post here for more details on the design process.

A unique feature of Labyrinth is the string of tiny spheres that lift and drop, reflecting the transfer of energy.

Hi, Mr. Roy,
I bought the Labyrinth a few days ago from Moonstones Gallery for my dental office. It worked in the first few days. However since two day ago, it has begun stop frequently. Today it did not even start after I wound the spring on. I was wondering if you could give me some clue about how I can repair it. Thanks a lot and I truly love this art piece.
