These presentations are made both in HTML (which is a classical web site) and in Flash ( the program for web animations, which offers plenty of interesting, dynamic, interactive contents, including music).

In order to experience Flash, you need to have Flash Player installed (though latest systems, such as Windows 2000, etc, automatically have it).But if not, you can simply download it from here. It is highly recommended to chose Flash site, because of its original "pen-made" cartoons and comics, backgrounds and animations.
