Mac OS X Cocoa gestures

I just started using BitArt Consulting's Cocoa Gestures Beta. Really excellent and highly configurable. The tool allows you to use gestures in any Cocoa-based OS X application. It won't work for Carbon apps like IE or Office X. It does work wonderfully well in the apps I tested it against -- Chimera and Adium. Adding gestures is simple too. You select "Cocoa Gestures..." beneath an application menu (below preferences) and add gestures by selecting menu actions and defining your gesture with your mouse. Nice. Would be even nicer if it worked with Carbon apps, which are the bulk of what I use (Entourage, Word, Photoshop, BBedit).

I wonder how many people are actually aware of and use gestures. I would guess that the number is miniscule.
