My #genuary13 self portrait is defined entirely by parametric equations! Portrait in the first image, equations in the second. The equations were generated by tracing points from a photograph, then basically using an FFT algorithm to convert the coordinates into paremetric equations. Each feature (head, hair, eyes, etc.) is defined by a different path.
