I've made an open source experimental authoring tool for such presentations here http://adityab.github.com/Awwation

It uses SVG, and Javascript for animations.

That's interesting, but in viewing the presentation the text is almost unreadable in Safari -- too much space between some letters, while others overlap.

If it works in Chrome, Firefox and IE... what's Safari doing wrong here? Oddly I just checked it on the iPhone and it seems fine there (although zooming out seems to be blocked, so the presentation is much too large for the screen).

That's a... bug. If you resize the window even by a slight amount, just once, everything starts looking perfect.

The zoom issue is a security limitation in iOS's Safari: iframes aren't allowed to hide content or zoom, so you cannot hide malicious elements. I've seen the same issues with presentations using impress.js, built using my tool[1]. However, that issue should be fixable by loading the SVG directly (or embedding the presentation inside a div, instead of an iframe.

That thing is awesome! Great work!
