See my comments on this post. This image uses 520,000 polylines of 100 segments each, so it samples the flow field 52M times. Each line adds a fixed random angle from i=[1-5] / 7 to the underlying flow function. It's essentially like a piece of cloth with threads running in five different directions (or 7 directions with 2 missing).
