Obviously you missed the demos ;-)
Have a look at
  site-packages/visual/demos/doublependulum.py
(or get that via
http://vpython.org/download/Demos-2004-07-22.zip
)

Best, Arnd

P.S.: BTW, I could not find any pointer to the demos on the web-page - so
maybe a link to demos, together with screenshots and links
to the code would be nice. (could attract some new users, I'd guess ;-)
