This is great!
As a Moai developer myself, I can't help but ask whether this work will find its way into Moai SDK? I am slowly writing my high-level Moai framework ( including importing SVG, 3D models from 3DS Max, video player, etc... the stuff I plan to publish as an open source) and I was looking into ways to accomplish bone animation myself. If the work that you do can possibly become a Moai feature that would be great as i could focus my time on many other areas that I still need to cover.
In the meantime, for us developer-dork-fans, can we get at least an "aerial overview" of how you accomplished this technically?
Thanks a bunch!
