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.
Impress.js is developed with current webkit-based browsers in mind (Chrome, Safari), but should work also in other browsers supporting CSS3 3D transforms and transitions (Firefox, IE10).
It's actively developed with newest Chromium and tested in Firefox Aurora.
I don't really expect it to run smoothly in non-webkit-based browser. If it does, just let me know, I'll glad to hear that!
For browsers not supporting CSS3 3D transforms impress.js adds impress-not-supported
class on #impress element, so fallback styles can be applied.
