Brusselator reaction-diffusion equations solved numerically

Here is a Java applet I wrote that uses Euler's method to solve the reaction-diffusion equations for the Brusselator. You can play with the parameters to observe a variety of temporal and spatial patterns. If you don't see the applet panel below here, you may need to "enable" Java in your browser. (To enable the Java language in the Firefox browser follow the following steps:
1. Under the "Tools" menu select "Options"
2. Click on "Web Features"
3. Check the box labeled "Enable Java".)

Here is the source code, in case you're interested: brusselator.java

Compare the steady patterns in the Brusselator with other things you've seen, like this: .
