19  * This example illustrates the use of <CODE>AnimationTask</CODE> in
20  * combination with the <CODE>VisualConnectorObject</CODE>. It renders a
21  * simple military tank that drives in a circle around the view area while its
22  * turret moves back and forth. The tank has a couple of connectors pointing to
23  * specific parts of it, and the connectors continue to point at the tank no
24  * matter where it goes.
