public class Dance
extends Applet
Dance - java.applet.Applet

java.applet.Applet for learning how to dance.

You can choose one of four dances and for every dance one of some figures and one of some music titels and view the animation of the figur synchron to the music.

The applet uses three threads for the animation and does an gread effort to make the animation as flickerless as possible.

Three attributes are currently supported:
english - use english texts
audio - default audio on/off
fatborder - use fat or thin border for the buttons.

Disclaimer:
Sorrie, my Java is better than my english. (My dancing is even better. :)
