Introduction:

No problem, if you have an Internet connection and a Java capable browser like HotJava or Netscape 2.0.

Load the Dance-Applet and look at the animation of (currently) nine figures of four different ballroom dances. With the single-step feature and the possibility to view the figures synchron to nice dance music you should have no problems to refresh your dancing skills.

Special Features:

• Two different languages built-in (german and english).
• Animation of different dance figures synchron to the music.
• Forward-backward stepping through the figures.
• Online help.
• Quick play-test of the different music titles.
• Additional information about every dance (only in german).

• Use of three concurrent threads to do the animation.
• No flickering through the use of Applet.update and Graphics.clipRect.
• Use of normal WWW-pages for online help.
• Use of derived classes and virtual functions for easy and clean programming.
