Cluster: Ingredients

As pointed out on the Technical Stuff page, the control panel consists of quite a few smaller images,

row1.gif, row2a.gif, row2d.gif, row2e.gif, row3.gif, row4a.gif, row4c.gif, row5.gif.

The applets use some images of their own,

balls1.gif, balls2.gif, row2c.gif, row4b.gif,

and a couple of sounds,

sound0.au, sound1.au.

The applet images, sounds and all the class files are never used directly, but rather compressed into a single JAR file, cluster.jar, which the browser can download as a whole. Finally, here are the source code files for the three applets, conveniently named "cluster", "right" and "bottom":

cluster.java
right.java
bottom.java
