I'm here to announce the latest app of mine. Called DroidGestures, it attempts to bring the ease and convenience of gestures to the entire Android platform. It allows you to use gestures from anywhere in the OS to launch apps and change system settings. Check out a video of it in action here:
You can get the app through the Android market. It comes in two forms: A free trial version that comes with a preloaded library of gestures and a full version that allows you to add your own gestures. Check it out and feel free to give feedback, I'm looking for some suggestions to improve the app before I release v. 1.0.
