lol I hope I didn't offend anyone with the jiblib comment, I just meant that there was a jiblib example very similar to the bullet demo and it ran very slow. All the other demos I saw worked just fine, it was just the one. :) Anyway yeah, great work all around I just think bullet will be great because of it's existing reputation. What I'm working on won't ADD to the flash bullet project, at least I don't see it at the moment. I'm working more on a tool for developing games in 3D like unity that will export to a single file and seamlessly integrate bullet + away3d to render out that file in flash. More details later. :)
