Basic framework for presentations using HTML5 + javascript

Question

Do you know a framework for making presentations using only HTML5 and javascript technologies?
I'm not talking about "export" features of various presentation software (powerpoint or OOo presentation).

Some requirements for the presentations made with this "framework":

• take advantage of the latest HTML5 features (audio, video, canvas?)
• same with CSS3 (font support, gradient, shadows, transitions and transformations)

If there's no such thing, example of good presentations or pointers on the subject would be appreciated.

Edit: Found a nice example, HTML5 - web development to the next level.
