Circle Sine Wave

Sculpture by Ron Geitgey

"Circle Sine Wave" is a disc of banded white marble with a rim in the form of a sine wave. I chose a banded stone and oriented it so the resulting hills and valleys would be emphasized by the color pattern. It is basically a very simple form with every diameter being a sloping straight line, but it required careful layout work and patience to carve successfully. It has three-fold symmetry, that is, there are three hills and three valleys mirrored on both sides, but from various angles its shape and color pattern appear to generate the two-fold symmetry of a rectangle or the four-fold symmetry of a square. The effect is especially apparent as the sun angle changes throughout the day or as the disc is rotated on its pivot pin.
