What exactly do you mean?
If you are talking about my particle_system patch, you *can* use any POV 
object with it. You could even have the camera follow a particle.

Now this is really confusing...nothing like that is done anywhere in 
POV...or do you mean something like the looks_like keyword, which places 
an object at the position of the light_source?
My original patch had something like that(custom_particle), but it was 
replaced with a get_particle function which is much more versatile. It 
just gives you the particle information, and allows you to do anything 
you want with it.

Are you talking about some kind of kinetics simulation system? So, for 
example, you could drop a pair of boxes on a plane and have them bounce 
to a resting position, like a pair of dice? And maybe have linked 
structures with inverse kinematics calculation?
It might be possible to add this sort of thing, maybe as a 
kinetic_system object which could hold particle_systems, cloths, 
strings, gels, and solid objects. The biggest problem, one which I have 
run into with my particle_system patch, is describing motion. I may have 
to resort to splines, but I would rather figure out some way of 
re-parsing an ordinary transformation which uses the clock value, like 
everything else in POV.
