You asked for feedback, and here it goes: I couldn't run your applet on my machine. It's not my intent to attack the choice of Java, but I can't avoid noticing that Java applets as a web technology are getting seriously obsolete these days. It's a challenge to get these applets running. JavaScript works way better on the web (I hate to say it, but beware the silly name: JS as a programming language has nothing to do with Java). The traceback follows. Exception was:
net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize applet. For more information click "more information button".

This is the list of exceptions that occurred launching your applet. Please note, those exceptions can originate from multiple applets. For a helpful bug report, be sure to run only one applet.
