This applet is very simple. When it starts, you see the title screen.
Click to continue. Now you are at the config screen. Set the options to
your liking and click the "Start!" button to continue. At this point the
screen will display a grid and the cockroach will start moving around on
it. Do not click the applet (it will queue the incoming events!) until the
movement stops and the cockroach disappears (presumably it got tired and
flew off). Now you may click it to return to the title screen.
