This week I am introducing Monarch II. This isn't really a new sculpture introduction like Swoop was last week. No, Monarch II is a tweak, a significant tweak, to Monarch.
Part of the joy of my job is the freedom to explore. I am constantly learning, evolving and changing my designs. I have modified Monarch to incorporate a variation recently refined while working on other ideas. There is a longer explanation about it here on the webpage but suffice it to say, although the motion, action and essence of the two is the same, there is a visual difference in the center.
In Monarch II much of the clutter has been removed. It just wasn't needed in this new, more elegant solution. I have learned that if I don't document these changes, and update the photos in the website, people notice and wonder.
I have decided, because there is a noticeable visual difference, I will close the Monarch edition (now Monarch I) at 36, and will start Monarch II with the next scheduled production run in June. This will be a new edition of 75.
People often ask where David gets his ideas and it can be a lengthy question to answer. Everything in life is an inspiration to an artist; it just may take a while for it to come to fruition in a creative work. Today, David is introducing his latest kinetic sculpture, Swoop and the original idea for this piece came from an 8mm Howdy Doody video from his childhood. David shares more about the origin and provides a link to the actual movie (now up on YouTube thanks possibly to someone else that loved it as a child as well) at the actual sculpture page here.

This piece is the combination of two new leaps David has recently made in mechanism design. Previously, his mechanisms always gave a power push through a minimum of 120 degrees. He needed to reduce the angle in order to give many small pushes verses one big push. To get the impact of the swoop motion he needed the smaller pushes. Swoop pushes through an angle of 60 degrees. He combined that new mechanism with a technique to have the front wheel move in an opposing direction without having a drive belt running directly in front of it. Those two "discoveries" allowed him to finally create the Swoop motion he remembered from the Howdy Doody film.
The Swoop mechanism works well in a smaller scale. So much kinetic sculpture is large scale and not appropriate for personal ownership. David has always tried to create sculptures that can fit in the homes. Swoop does that a bit more easily than some of his recent works.
David just released the video and photographs of his second new sculpture edition for 2012. It is the birth of a butterfly, not because David designed a butterfly, but because that is what viewers see now that it is a reality. People often "see" things represented in David's work.
Check out the YouTube video to see the motion of this mesmerizing kinetic sculpture.
In this design, David decided to make the mechanism very visible. He opened up the front and put all the parts right there for you to see. Those of you that have been studying David's work for years can really observe an escapement mechanism in action in this design.

I’m often asked how long it takes to design a sculpture. My normal answer is that it varies, it can be days, months or even years. I think Labyrinth holds the record for length of time from conception to final execution.
I started working on it in 2007. The inspiration came from an animation I found online showing an interesting optical effect created when multiple parallel straight lines are rotated in opposite directions. (Unfortunately I can no longer find the animation.) I loved the dynamic patterns created and started a set of animation studies of my own. I wanted to see if I could extend the concept to wooden wheels. The practical constraints were different of course. Wood lines have to have a certain thickness and they need to be tied together with a hub and a bearing system. I played with dozens of different designs, drawing in Adobe Illustrator and animating in After Effects. I found that if I curved the lines and tied them together at the rim I could retain elements of the original concept but add a subtle shift in the dynamics. Of course it could be that I just prefer curves!

The wheel design turned out to be the easy part. Next I had to design a mechanism to move the wheels at the pace and in the directions I had developed in the animations. What is easy to do on the computer screen was a completely different challenge in the analog world! The wheel closest to the wall was the work horse. It had to rotate in both directions and occasionally give the front wheel a little nudge. It had to do all this while moving slowly so the patterns could evolve and flow at a pace that felt right to me.
The problem was the wheels were heavy and took a lot of energy to get moving and even more to stop and reverse direction. I thought I had a solution, two separate mechanisms that that would work together to power the sculpture. The mechanisms would work together with one side rotating the back wheel clockwise and the other side counter-clockwise. Each side would have its own drive spring so I would have ample energy to play with. I built the complete sculpture and it worked, sort of.
The patterning motion was as I had hoped but the sculpture was hard to set up and operate. It was also very inefficient. I was using two drive springs and only getting around 5 hours of run time. It was also difficult to keep it from stalling when I had the wheels moving slowly enough. I brought the sculpture down to the house and set it up on the “preview wall” in our dining room so we could live with it. It was there long enough that my daughter’s boyfriend (and now husband), Jared came up with the name. In the end I took it down and packed it away, it was too complex and unreliable. I felt a little bad because it was a great name chosen by the newest member of the family but the mechanism was a failure. (Naming sculptures is a family and friends challenge because I'm so bad at names!)
A few months ago I unpacked just the patterning wheels, spun them by hand and decided they were worth another effort. I have learned a lot about mechanism efficiency in the past 5 years and had some new ideas about how to handle the large wheels. The result, using a new mechanism design, was far different this time.
The sculpture produces exactly the motion I wanted, it’s easy to set up and operate and it runs for a bit over 12 hours on a single spring. The key is the 5 little wood balls you see marching up the string; actually not the balls but what they are covering, a short section of coil spring.
This spring absorbs the extra energy of the rotating back wheel when it comes to the end of its rotation in one direction and then feeds it back to the wheel but in the opposite direction. The rest of the 2 lever mechanism is also new but the use of this spring to aid in the change of direction was the breakthrough. Sometimes patience and frustration pays off!
The new Labyrinth operates for over 12 hours on a single spring wind. The mechanism is flexible and reliable enough that I could set exactly the pace I wanted. It’s also far easier to install and operate than the old version.
