Please take a moment to fire up your browsers (all of them) and check out 20 Things I Learned About Browsers and The Web - an impressive online book done entirely with HTML5 that tells the history of Interneting and computing. Even if you have no interest in the contents of the book, the presentation is well worth partaking in. The transitions are smooth, the URL is clean (especially in Webkit) and, frankly, I've just not seen anything like it before done with the tools used (it's nothing new for a Flash site but pure HTML / JS is worth taking note of).
