Mouse Gestures the Easy Way. You can create a single action, or chains of actions to be invoked by the simple movements of your mouse. Instant feedback so you know you are on the right track. Easy configuration to make your own actions. FlyGesture works alot like Automator.

FlyGesture is activated like Exposé or Dashboard, bringing up a transparent window of "guides" to move your mouse through. Moving your mouse through the guides lets FlyGesture know what action or actions you want to be performed, such as closing a window or opening an application.

Requirements:
OS X 10.4
Universal Binary
