One of the most exciting features of the Rolling Ball Sculpture is the track. The track provides a means for the balls to move with speed and grace through the machine. I can build many different track layouts to whatever specifications are desired. Below are some of the features of my track layouts and how they are implemented.


Track layouts are highly dependent on the lift systems, track elements, and overall display size. For instance, the Mechanical Engineering Demonstrator's track was designed mainly as a means of travel from one track element to the other. Since track elements were located in different places throughout the display, the track had to curve and loop to avoid getting in the way of other track and elements. To make this more apparent, look at the photo to the right. This photo shows the Mechanical Engineering Demonstrator from a front view. Though it appears sufficient space exists between the tracks, the photo does not show the true compact, twisting nature of the display until you view it from the side. The photo to the left is a side view of the Demonstrator.
My Rolling Ball Sculptures incorporate a two-rail track system throughout most of the display. The two-track rail system is, in my opinion, the most elegant of RBS styles. This is because having two rails requires banking to keep the balls on track. The banking creates smooth lines and decreases the amount of extra rails. It also makes the physics of the display much more interesting as people wonder how the balls stay on track.

The track system can follow many different paths between lifts, switches, and track elements. Usually, I determine the locations of the various elements and let the path of the track evolve independently. This continuous evolution makes the sculpture seem to live and breathe on its own, even when not running.
