This is a fine animation. Congratulations for syncing sound and getting a good narration voice. I guess you used a JS library to achieve this. My difficulties with CSS3/HTML5/JQuery animation as of "t.o.d.a.y" are:

1. If one has to programmatically create all animations, then browser based animation is at same stage as 1985'ish BYTE issues where drawing a chess grid in CG was a major achievement. A lot of great animation work is done by animators who don't code or won't code (http://www.ninapaley.com). Flash provides timeline to achieve this. The newer Edge is nowhere close to that level of fineness. Where are the tools for animators who animate to create these animations? (Psst. We need another Flash!).

2. Most of the current animation we see in CSS3/HTML5/Jquery is boxy, geometric stuff. Where are animated characters? and how easy is it to do it all in one environment like Flash? I am not a banner holder for Flash but it did provide a good integrated environment to draw, animate and code too.

This is neither a rant nor any stand. I am just wishing that tools develop faster and better so that animators who visually create animation can do cool stuff in browser based animations.

Thanks for sharing a nice work of art :-)
