Bubbles moving away from mouse

I need some help! I am developing a flash movie where a series of bubbles softly and continuously float up from the bottom of the screen to the top. When someone mouses over and area of the bubbles, the bubbles need to softly repel away from the cursor and continue floating away from the cursor. Does any one know a script or an example of a source code or file that has or is similar to this functionality?

Thanks so much in advance!!!
