How to make a scatter to repel particles away? Opposite of atractor.

[kockaart]

The effect would be like this: LUMOplay | Interactive Floor and Wall Games
The particles move away for a distance and than move back if the scatter out of range.

This one might give some ideas: 4.12 Particle Systems with Repellers

Make the force the opposite of what it is in the attractor.
