I’ve long been fascinated with the segmented structures of larvae and of spinal forms and their ability to express elegant motion through waveforms and writhing. Undulum is the first attempt in a series of sculptures under development inspired by sinuous motion in nature.
The mechanism of Undulum is deceptively simple and consists of a helically shaped rod that rotates within a flexible sheath, which in turn is anchored. A second, outer, sheath is built of translucent acrylic shapes held apart by preloaded flexible foam spacers and is also anchored. As the rod rotates within the core of the sculpture, the outer sheath rides the convolutions of the inner sheath as it contorts to follow the changing shape of the rod within.
