Chaos Game Applet

[flwyd]

I spent most of yesterday and the first part of today writing a Java applet implementation of the Chaos Game. I find that the color schemes help significantly to understand why configurations lead to the patterns they do. The original description (which explains verbally better than I have) just featured monochrome images.

While I write Java code every day at work, most of it is data-focused. Data-focused GUIs (put this field over here, put these buttons in this panel over here) are important and often tricky to get right, but it's been years since I did anything with public void paint(Graphics g). Playing with code which requires no database, no metadata configuration, and no client-server communication was also refreshing.

You'll need at least Java 1.4 to view the applet. I compiled from Eclipse running under Java 1.5 and while I don't think I used any new API methods I didn't have a 1.4 JVM convenient for testing. Let me know if you can't get it to work.

Shoot. The combo box (a lightweight component) is probably getting obscured by the Canvas (a heavyweight component). This is what I get for testing on OS X where everything is a native component. I'll test with Linux and see if I can come up with an all-lightweight solution. You should be able to change selection with the up and down arrow keys, though.
