Nothing I'm aware of.

Sort of. One reason is that DPH does not seem to be ready for hpysics
yet, another one is that I don't see any potential users around (read: I
just need a kick in the ass).

Yes, I'm actively pondering Hpysics+Grapefruit (it's the primary reason
of my interest in Grapefruit). But first of all we need to get graphics
support into Grapefruit.

Does your proposal re Hackathon indicate that you'd like to join?
