Not exactly the same but on topic of nature's template displayed, I noticed these patterns in the mud spray on my work truck. This is never driven above about 35 mph but look at those pretty little templates trailing the rivet heads. Also the trailing part of the feul door and the separation on the too radiused curve on the back. Part of this must be the effect of the rivets cleaning the heavy dirt out of the air but I thought it looked cool and reminded me of the teardrop template.
