The hedcut algorithm

Super interesting thread on using Mathematica to approximate Wall Street Journal–style hedcut portraits. Okay that probably doesn’t make any sense. Just click through; you’ll understand. It’s fun to watch them work through the problem.

Have you seen StippleGen? Built in Processing, uses a Voronoi algorithm to approximate the dot pattern. It laser-cuts like a dream.
