More polygon doodling has produced this pattern. I have created the local patterns before but I believe this is a new one. I may try a bit more variations using the arrowheads. I do have a bit of race conditions when filling the centre of the vertices (the things that look like the plastic piece that you would put in 45 records--OK, I'm old). I would prefer a bit more regularity but for this small patch it's not a bit deal.
I like the way my mind flips between the purple and green patterns, the vortices, and the arrowheads...
