This must be what Hans was talking about.

Well, actually I'm using ConTeXt/MetaPost to generate each frame of the
animation "automagically".  The webpage will soon allow for downloading the
source for each ConTeXt document.  This generates a multi-page PDF where
each page of the PDF is a frame of the animation.  SWFtools (specifically,
pdf2swf) can then be used to convert the PDF to SWF.
