I've created several animations using MetaPost/ConTeXt, and I have also
created a webpage with these animations.  The URL to the page is

http://www.tlhiv.org/animations/

Feedback is appreciated, and if there is a particular animation that you
would like to see included, let me know and I will attempt to code them up
in MetaPost, provide the source code, and include them on the webpage.
