Looking for swirl effect

Hi guys,

I’m looking for any AS3 script that might help me create a dynamic swirling effect. I need to apply this effect to a dynamically populated movieclip and presumably it uses bitmapdata and flash filters to work… Just can’t get my head around it. Specifically I’m looking for something similar to this;

Any help, examples, pointers would be really appreciated.

Ta very much,

Steven.
