FLASH effect needed for dynamic text

I need an effect created for a Flash website that will be applied to scrolling dynamic text. The effect that needs to be created is a scrolling fisheye/carousel effect. The text in a box will scroll and as it approaches the middle it will gradually increase in size - after it passes the middle it starts shrinking to it's original size. I've attached an image to better explain this effect. If you have done something similar please let me know. Thanks
