Background: A business partner that I did some work for a couple years ago hit me with an interesting proposal, a large oil derrick interactive Rolling Ball Sculpture for a Mini Golf Course he was building. I agreed and we started brainstorming, shown in the picture was the first version of the 3 section base its built on. We made a couple design changed to the frame and now the track is currently in progress, with many interesting features. The interactive portion will be shown once installed on site at The Putting Mill in Spring Branch Texas.
