Quite an impressive piece of work! impress.js aims to replicate the prezi.com presentation style in the browser by taking advantage of CSS3 transforms and transitions.
The demo is quite slick, especially the kicker at the end. Neat stuff!
It’s really rare that I make a presentation anymore, but hopefully when I’m able to get into speaking in one way or another, this little tool will come in really handy. I’ve heard all too many times about Keynote decks going haywire and losing tons of work, this seems like a way to get things just right and a bit more stable.
