Rotating to a specific pos?

Hi,

I’m about to do a menu-system for a pretty wicked site. Not that this menu-system is wicked it’s just that I don’t get smarter in how to do this. I have searched the net without finding anything similar (but I guess this is pretty simple).

I’ve got an image (from a synthesizer), seen above. My vision is that the center-controlling-device is rotating to a specific spot when clicked (ex: Clicking the “4” will make the center-device rotate so that it points at it).

The center-device is a png24 cutted out from the image - placed in flash.

Anyone knowing a tut or a simple way making this reality?
