Macchina Naturale (Natural Machine) by David Boyer is a large kinetic wind sculpture reminiscent of a whimsical machine from a bygone era. Industrial elements blend with an organic tree-like form to create an amalgamation of the man-made and natural worlds. With their canopy of motion, light, and shadow, large horizontal paddle wheels create a contemplative Zen-like space. As our ecosystems are increasingly under assault, may this environmentally interactive sculpture be a reminder of our need to work with, rather than against, nature.
