> https://www.science.org/content/article/jaw-dropper-crop-circle https://www.science.org/content/article/jaw-dropper-crop-cir... All parts are based on a circle ("arms" are just incomplete circles). That's a stick in the ground and some string. Start with the big circle in the middle. Why 6 arms? Because then distance between biggest arm circles is the same as the distance from them to the center circle. Easy to put them evenly around. I'm sure it still takes some time to make them, but the figure is neither complex nor accurately done. I don't see why a few bored students couldn't do it overnight.
