The first of a pair of very large floor standing Rolling Ball Sculptures. Standing at 7.5ft high, 8ft wide and 15" deep. This RBS has 4 different paths with several large elements. 

I started on this project with the very large loop d' loop in the center of the frame. With lots of room left to spare I added two more loop d' loop sections for a total of three different loops all on one track.
