Spinning String Lightform
From the Visual Music page of Paul Friedlanders website.
Paul Friedlander is an award-winning kinetic light artist and the creator of Zip Art, an image-drawing program.
He says, In this illustration, you see a spinning string vibrating in harmony, this description sounds like a musical instrument, but it is a light sculpture. The vibrating form is a superposition of the second and fourth harmonic: a visual chord.
