Had some issues (see my youtube channel) but finally have Box2D doing object seperation and collision detection for my work-in-progress indie game "Box Mental".

All I can say, is that Box2D rocks. I'll definitely be playing with the flash version for another prototype idea I've got. Next up for box mental? Well, need to update the navmesh generation so that it can handle arbitrary scenegraph nodes. Also need to add collision shapes to those various objects. Then work on some more interesting behaviours/animations. Plan on submitting to the sony compo this week too.

More soon.
