All the work that I have done is used impress.js to create a webpage. It is very simple and intuitive.
You may want to see my website to see it in action. You can view the source code for this here.
It's a presentation framework based on the power of CSS3 transforms and transitions in modern browsers and inspired by the idea behind prezi.com.
WARNING
impress.js may not help you if you have nothing interesting to say ;)
Use the source, Luke ;)
If you have no idea what I mean by that, or you just clicked that link above and got very confused by all these strange characters that got displayed on your screen, it's a sign, that impress.js is not for you.
Sorry.
Fortunately there are some guys on GitHub that got quite excited with the idea of building editing tool for impress.js. Let's hope they will manage to do it.
More examples and demos can be found on Examples and demos wiki page.
Feel free to add your own example presentations (or websites) there.
If you want to learn even more there is a list of tutorials and other learning resources on the wiki, too.
There is also a book available about Building impressive presentations with impress.js by Rakhitha Nimesh Ratnayake.

It's an (un)fortunate coincidence that a Open/LibreOffice presentation tool is called Impress ;)
Free to Distribute and personal use. :)
