Below is a list of files that you need if you want to run the applet from the comfort of your own home. DrawBiomorph.class is the main class so this is the one you should run. Unfortunately you do need every single one.
Or you could just click here for the zipped archive, which includes an html page to run it. Just unzip into a single directory of your own choosing and open the html file called "3DBiomorphs.html".
