The development of the sculpture is the end of a design odyssey that started with Sky Dance, moved to Falcon and culminated with this sculpture that I'm calling Journey. In each of these pieces I've created different mechanisms to explore what I call "bird" motion, that is, varied horizontal, vertical and spiral motions that are more or less random.

This sculpture was the most challenging of the trio. I almost gave up on it. The idea was to use my Pegasus mechanism to power and control the motion but no matter what I tried, I couldn’t get it to perform the way I wanted it to. The motion was too quick and there wasn’t enough variation. After several months of failed attempts, I found the solution – more mass in the middle wheel and 2 small springs for power. This smoothed out and varied the motion and had the side benefit of extending the run time. After 30+ years of designing kinetic sculptures I’m still learning, it's frustrating at times but lots of fun.
