About Nexus Arc

One of my joys in semi-retirement is the time to fully explore new ideas. Nexus Arc is the second part of my exploration that started with the sculpture Storm released in 2021. With Storm I used 6 separate mechanisms to create a “stormy” mix of 6 independent elements. 

Nexus Arc is a study of what happens when I use 6 wheels set in a Storm’s radial pattern but synchronized. I incorporated a different mechanism to achieve this variation. The result is a completely different pattern that seems to collapse toward the center and then burst out again but all in a repeating and orderly fashion. The rotation starts out fairly rapidly but over the course of several minutes gradually slows down and finally stops and reverses. This reversal is the signal for the spring-based mechanism to give the entire assembly another push. The cycle time is long so during the beginning of the video I cut out 90 seconds of time so you can see both the start and end of the motion quickly. The video then continues and shows the full cycle. 

If you listen carefully you can hear 1 click per rotation and a louder click then the main push happens.

Nexus Arc creates endless evolving patterns as it moves. The still photos to the right shows three of its many different orientations.

About Thunderbird:

I designed and built this sculpture in 2016. It was partially inspired by my sculpture Infinity but I wanted a pattern that was more complex. Infinity had a pattern that was fairly simple.  I designed a chaotic mechanism to drive the pattern in unpredictable ways. I wanted to try the inverse,  a more complex patterning wheel with a predictable drive mechanism. To this end I started playing with an inside out wheel where the spokes were asymmetrical. Asymmetrical wheels are harder to design because finding the balance point is not a simple matter of just finding center. The mass of each section of the wheel has to match its opposing section on the opposite side of the wheel, regardless of the shape of that particular section. I love this kind of challenge. It often reveals interesting patterns. 

I draw my parts in Adobe Illustrator and then animated them in Adobe After Effects. The calculation of center of mass is accomplished in a program no longer produced for the Mac called Working Model.  I use a vintage Mac to run this software and it still preforms admirably. 

The result was a new pattern that I really enjoyed. I decided to drive it with a double spring long running mechanism and live with it in our home. I like living with long running sculptures because my workday is filled with winding and I don’t need more at home. 

The more I watched it the more I wanted to share it. I decided to simplify the wheels a bit using fewer, somewhat thicker spokes and power it with a center drive mechanism. Eventually this became Duality which I introduced in 2017 and it became a collector favorite. 

So now it’s years later and although I still enjoy my long running Thunderbird it’s time to sell it and make room for some new designs. I’ve been doing a lot of designing since my “retirement” and I need the wall space!

About Complexity 3

My edition sculpture Boomerang was the result of a systematic study using patterns created by the swept-back spoke design. I’ve been experimenting with this type of pattern for years but never systematically. In my retirement I decided to take the time to do a more detailed study. In this phase of the study I varied the number of bends in the spoke; Complexity 1 has one bend followed by Complexity 2 with two bends and 3 bends in Complexity 3. My normal working method of studying computer animations was not definitive so I decided to make all three and compare them side by side. The time to do this is another luxury of retirement. Each sculpture had it’s own qualities and I liked them all. In the end we chose Complexity 1 to become Boomerang.  But…….

Complexity 2 and 3 are both fascinating sculptures so I’ve decided to sell them as one-of-a-kind sculptures. In the past I would have hung on to them for future editions but there are too many new ideas to try and not enough time to do it all.

About Boomerang

Boomerang Kinetic wall sculpture by David C. Roy of Wood That Works ©2021

I started experimenting with “switchback arms” in my patterning wheels as early as the 1980’s with sculptures like Star Shadow and Crystal. It wasn’t until Illusion in 2005 that this pattern started to come together. This led to Radiance in 2007 and Shimmer in 2009 which were smaller more accessible sculptures that basically used the same patterning wheel with completely different mechanisms. In 2018 I returned to the switchback spoke for Deja Vu because I had a new mechanism to try with a large patterning wheel. This concept generates seemingly endless pattern variations with just a small tweak in the spoke’s shape. 

Boomerang is an extension of this design path. This sculpture creates yet another interesting pattern by using a shape reminiscent of a boomerang as the switchback spoke. The variations are endless. I liked this one because it creates a pattern that is both familiar and completely new. It reminds me of gentle waves in a small pond that are growing and shrinking at the same time as they interfere with each other. 

This is a long running sculpture (around 20 hours) that uses only a single spring. I designed a simple symmetrical base and winder system the lets the pattern do all the talking. The recording has no music so you can listen to the wooden clicking sounds generated while in motion.

Calligraphy

About Calligraphy

Two years ago, I introduced what I am now calling Calligraphy Prequel, a sculpture with an interesting chaotic motion. Despite its uniqueness, I never offered it for sale due to its frenetic and noisy nature, which proved to be more disruptive than I had anticipated. It was a sculpture I couldn’t envision living with, let alone anticipating others enjoying it.

Over the past two years, I've been experimenting with and refining Calligraphy. The joy I find in retirement is having the luxury of time which allows me this continued exploration. The sculpture now runs for longer periods, is quieter, and the motion is significantly less frenetic. The updated mechanism has evolved to behave more like the one found in my sculpture Chaos, incorporating quiet intervals of non-engagement seamlessly interspersed with bursts of energetic dances.

I’ve left the original Calligraphy page including the video on the website here. The narrative detailing the decades long development of this piece is shared there. Those of you that are interested in the nuances of my work should compare the two videos. Can you perceive the difference in the motion?

I hope this helps! Let me know if you have any other questions.

About Kindal-Celebration

Kindala - Celebration is a kinetic wall sculpture by David C. Roy of Wood That Works

The Kindala concept which has been explored in a number other designs has been re-visited in this sculpture. The mesmerizing  slow unfolding of intricate circular designs continues to fascinate me. This is the most complex Kindala pattern set I have attempted. The pattern reminds me of starburst fireworks. Hence the name Celebration. 

I use the same base and drive system in both of my long running introductions in the 2021 design period. I like it because it is a step away from the designs like Duality based on pattern wheel only but has the long run time and easy wind that I like to live with. Celebration wins the run time award in the 2021 designs coming in a couple of hours longer running than Boomerang. The Kindala type of motion requires less energy so runs longer. 


Why Kindala?

Kindala is a made up word I created by combining Mandala and kinetic. I thought this series needed a distinctive moniker. Every design has a circular design like a mandala and they all move but each has visual distinctions in the wheel design or power structure.

About Vice Versa

Vice Versa in a kinetic wall sculpture by David C. Roy of Wood That Works

It often happens that one sculpture starts the idea for another. This is especially true at this late stage of my career where I have explored and given up on many ideas. In 2016 I explored a new concept in a one-of-a-kind sculpture called Blink. I explored what would happen if I reversed the normal order of fans in a patterning wheel and had them point in opposite directions. Of course this created a significantly off-balanced wheel but I compensated using a large outside frame ring that varied in width. This was a difficult sculpture to make because even with the outside ring, balance was still hard to achieve. I did enjoy the “blink” effect and the varied patterns but thought it too challenging to produce in an edition. 

These are the types of challenges I’ve been enjoying revisiting now that I’m “retired”. Last year I decided to explore whether this really was an impossible wheel to balance. Using my ancient copy of Working Model software along with my favorite drawing program Illustrator and a spreadsheet I ran numerous simulations looking for a design with the center of mass at the center of the wheel. I played with the number of spokes, their thickness and their angle relative to each other. Eventually I found a design that I thought would work both visually and dynamically. I tested the patterning by generating an animation of the design in motion. Of course the real test was to actually make the design. My first attempt wasn’t quite right. It was still too off balance. I tweaked the design and refined my center of mass calculation to more precisely locate the exact point. The second attempt worked as I had hoped. 

I love the mix of 3 different patterns during each rotation. Half of the pattern shows as collapsing fans while the opposite half is expanding. Just as that becomes recognizable everything is wiped away in a blink pattern. The constantly shifting rotation rates combined with this pattern creates a piece I find hard to stop watching. 

Fraud Warning:

Apparently there is a concern out of China that is currently putting up fake websites, instagram, tiktok and facebook posts offering David’s designs for $39- $59. All have stolen videos and images from our website and David’s IP. No one has been given permission or been licensed to use these designs or images. If you purchase, some sites steal data while others ship you wood scraps. None ship kinetic sculptures. A number of kinetic artists are experiencing this. The “companies” dissolve and new websites appear every other day as the previous ones get shut down due to complaints. Additionally now they are selling “kits” on Amazon. These are wooden parts taken as screen shots from my designs. They are incorrect, incomplete, without instructions and will never work. Please report them as fraud. They have no connection to me what so ever! Thank you.
