Is there a script for an advanced "knock back" which flips units around?

Knockbacks are common nowadays, I am wondering if anyone of you clever folks have tried making something which simulates a huge explosion knockback.

The first "step" would probably be a knockback script which flings a unit at a certain arch while flipping it around randomly. But if this works well then it sould be able to lend a way to an area knockback.

So let's say a missile impacts an area with units, etc. clustered around it, then all the units will fly all over the place (away from the centre of the explosion), but it wont just move back but fling and spin randomly too.

This would make for a pretty awesome explosion filled map don't you think? It's going to be like if Michael Bay made a map ha ha...

BOOM *flip fling spin*

The problem is making the flips. You could always use the dummy.mdx with a special effect for the model (for flipping with the animation indexes), but either way it would be pretty hard to coordinate. =P
