76 Uses a simple simple motion model to generate many different display
77 modes. The control points attract each other up to a certain
78 distance, and then begin to repel each other. The
79 attraction/repulsion is proportional to the distance between any two
80 particles, similar to the strong and weak nuclear forces.
