Are There Any Customizable Particle Simulators Like This?

[Misero]

Any good particle simulators with adjustable mass, gravity, repulsion. (3D would be nice, but I don't need it to be 3D)

This is too vague. Particles of what? If there is gravity, why is there repulsion? I have no idea what you want.

As in, I can either make them attract or repel with number values. Particles as in sort of circles floating around. Sorry if I was a bit vague.

That's not any clearer.

I think he means flash physics engines

Here are a some

Yes, like those, but with a bit more customization if possible.

I think you'll need to program one yourself :)
