+Uses a simple simple motion model to generate many different display
+modes. The control points attract each other up to a certain
+distance, and then begin to repel each other. The
attraction/repulsion is proportional to the distance between any two
particles, similar to the strong and weak nuclear forces.
-One of the most interesting ways to watch this hack is simply as
-bouncing balls, because their motions and interactions with each
-other are so odd. Sometimes two balls will get into a tight orbit
-around each other, to be interrupted later by a third, or by the edge
-of the screen. It looks quite chaotic.
