Yes I just started a wrapper for Bullet : http://github.com/flupke/ballistics It looks very similar to yours, except that I try to closely stick to the C++ API (names, modules organisation, etc...), so I can avoid rewriting the whole documentation :) (I will eventually add helpers to ease setting up objects) For now, I ported the Hello World example from the tutorial (see ballistics/tests/dynamics/world/test_discrete.py) and got a ball bouncing... There is still a long way before wrapping the whole API !
