What's a good way to have particles move around slowly in a constrained space (using newtonian physics)? I've tried to do this various ways, say to simulate dust moving around a room in a dream like way, one way I'm currently using, but is a bit unpredictable, is to have a collision object shape outside of the particle emitter, and then a force pushing around the particles. However I find that the particles tend to gather in uniform path pretty quickly, or bounce too wildly off the walls of the collision object. Any ideas? would be greatly appreciated.

    Hey, try using a really big emitter that takes up almost the entire room. Then set the particles to emit from the volume instead of vertices or faces. Next, turn off gravity in the Field Weights and turn off any emission velocity. You could then use a turbulence force field with a low strength setting to make them move around slowly.
