What I enjoy most about kinetic/rolling ball sculptures is their ability to captivate an audience of all ages on many levels. This for me, makes them hugely rewarding to make. You could describe them as a marriage of artistic ideas with engineering, presented as tangible moving objects.
The processes which I liken to “drawing with wire” evolve from a rough set of plans into a finished working piece made from stainless steel, which is tig welded and won’t deteriorate over time. The motors that drive the lift system are designed to be easily replaced if necessary at a very low cost. A 12v charger for the motor draws only half an amp, and led spotlights where used means it won’t use much electricity to run. Timed operating is also possible throughout the day if required and ideas for wind, solar and water powered versions are on the drawing board.
