Nearly all of David's kinetic sculptures are powered by springs. Early in his career he used descending weights but he has never used water as a power source. These sculpted downspouts crafted out of copper do use water as a power source.
Their combination of whimsey and mechanics appealed to me. I thought many of you that enjoy David's work would also appreciate the creativity of these downspouts. They are designed and crafted by Vladimir Sumchecko, a Ukrainian immigrant located in the Pacific Northwest. His website is Art of Rain.
