Hertz (2012)

An ArtGraph often starts out as a simple mathematical shape.
Often the original shape is lost as the composition develops.
Not so with Hertz.
It's essentially a sine wave, roughed up a bit, and with some random colours thrown in.
A nice example of a basic ArtGraph.
A beginner who was willing to spend a day or two playing around with the
ArtGraph software could reasonably hope to construct something like this.
