There's a java applet here to show a simple version of the structure, and how it varies with the algorithm parameters. Drag the sliders (by the line between the colours) to change the parameters.

The applet was built with processing, although the structure was originally coded in rhinoscript.

WARNING: the applet is quite resource intensive and may crash your Firefox. Internet explorer seems to cope ok. Also, it needs java, and could take a few minutes to load.

Play with java applet now
