Voronoi Portraits

While experimenting with different generative systems to make a knitting algorithms out of I ended up with these interesting Voronoi diagram portraits. Searching with expanding co-centric circles, if a point was under a certain threshold, I marked it for the center of a voronoi cell and generated the diagram from it.

I'm actually trying to find a decent system to make lace or cables from, so either a distinct holey geometry or overlapping pseudo-chaotic paths. Flocking actually would be perfect, but I confess, I'm actually quite sick of it and I want to try something new. The Voronoi didn't work out (its a bit too regular), but they still were an incredibly fun exercise.
