Bounce.js

All in one JS powered web app to rapidly generate fast cross-browser animations, written by web developer Joel Besada. It just came out today, but my first impressions are very positive. Instead of downloading a clunky, bloated Mac app for doing CSS3 animations, this feels a lot fresher and more lightweight. I was able to put together a fairly complex CSS3 animation quickly though I haven’t inspected the exported CSS in detail yet.
