simple rotator

[PeteC]

1) Instead of vortex force, maybe you could just simply use path follow. Make particles follow the circle, and you will probably need slow operator bellow it. 
2) Just turn of the display, and the dots will disappear. You will still see yellow mesh of the cloth. 
3) Never noticed voronoi creates shell like surfaces. Actually, it works perfectly. If some (for example) box have a shell on it, then it will have shell, if it doesn't have shell, it will brake it regularly. Maybe you should check your mesh if it is closed completely.

Thanks for your answers! The problem with path follow is that the particles are attracted to the path and you get a rotating ring, instead of a spherical field, of debris.

I'm not sure what is happening with the veroni fracture, but currently its creating 3D rubble out of 2D sheets, but I might be doing something dumb, very likely. I'll simplify the setup to one test object and see if it works. anyway, thanks

cap holes was on, it was creating mesh to patch the backs of the sheet fragments
