SNAIL TRAIL LAB:
They each reflect each other and makes it perfectly symmetrical. First you make a hexagon made out of lines. Then you put one dot in one of the regions. Then you reflect it over the line (this is the line of reflection). Then you do the same with that one, etc. Then put show trail and rotate them around the circle. I noticed it is the same on the other parts of the circle making perfect symmetry. It is line symmetry and rotational symmetry.
