Customizable "hot corner" application launcher.
The BIG Red Button works very much like the Mac OS X built-in "hot corners". The big difference is that the red button lets you launch any application or AppleScript you want; something that you cannot do with the built-in hot corners.
When you work with a lot of applications at the same time there's usually one that you return to frequently (e.g. Mail, Safari, Photoshop). The BIG Red Button is for that app. Push it, the app comes up. Do your thing. Done.
