We will try to make the demos and their source code available on this web site as zip archives. For the time being, the web site offers a link to the project page where you can find the CVS repository. This web site is still very much a work in progress and has been tested only with a few web browsers so please forgive me would you encounter any problem.
Update: The web site has now been tested, fixed and tested again with Internet Explorer 6. You should now be able to view the web site in good conditions.
