Not sure if this is the right place to do this, but if not, I'm sure someone will point me in the right direction.
I've just finished developing an application called DroidGestures. It takes the ease and convenience of gestures (think like the ones you use in your browser) and allows you to execute them anywhere in the Android operating system. For more detail check out my introductory post about the program Introducing DroidGestures | DroidGestures Development Blog (includes video of the program in action)
Currently the application is in Beta. I have free and full versions in the Android market, and am eagerly awaiting community feedback so I can add more features / perfect the program before its full 1.0 release.
