I've not been on the boards for a while, as I've been working on a different project, but thought I'd share with you what I've been using Bullet for, now it's gone public!
I work at Framestore, and spent several months last year developing a tool called "fBounce", which allows artists to run Bullet rigid body simulations through Maya. The tool has been used on a few productions now, but the only one released so far is Sherlock Holmes, which won the VES award for Outstanding Supporting Visual Effects in a Feature Motion Picture. There's an article on the fxguide website about the effects, which mentions fBounce twice!
So, thanks to everyone on here who helped me out when I got stuck - I reckon that award must be a little bit yours too
