Bouncing balls in a circle gives one of the simplest systems to exhibit chaos, as was pointed out in a comment by Andrew Moylan. The animation above shows two balls which start off with almost exactly the same speed and location, but before long they are travelling along completely different trajectories. Such high sensitivity to the initial conditions defines chaos.
In this visualisation, each point in the circle is given a colour in a rainbow pattern. The animation shows at each time where a ball dropped at each point within the circle has ended up, by colouring that point appropriately. For example at the first frame, all the balls are stationary, and we see the rainbow pattern. Then as time progresses, the balls drop down and the pattern correspondingly goes up. A black band appears and moves up, which shows which balls are doing their first bounce. Soon the order disappears- it looks random like the divergence of the two balls above.

Wound Man is an illustration which first appeared in European surgical texts in the Middle Ages. It laid out schematically the various wounds a person might suffer in battle or in accidents.
It would really suck to be wound man.
