Change the Identifier of the timer by clicking inside the white box, then type your text and hit "Return", or click anywhere inside the applet. When a countdown has run off, a sound is played for about 10 seconds, unless you click anywhere inside the applet to stop it. The sound file is looped. It must be named "alarm.au" and must be inside the applet directory. The Colors for the Timer and for the Background (should be the same as the HTML-page background) can be specified via parameters. When you count down, you can tell by graphical gauges how much time is left. On count up, animations are visualizing the running timer.
