I can't seem to find any, anywhere and I would really like some extra functionality for the MacBook Pro Trackpad. Specifically, I would like the ability to use a three finger swipe up and down to go to Application Exposé not All Window Exposé.
I use two finger rotations to turn the volume up (clockwise) and down (counter clockwise). There are a bunch of other predefined gestures and you can choose what they do. You can also use your own.
