Post your favorite freeware application for Macintosh here! (preferably with a link!)
Hopefully we can all find about some interesting programs that we otherwise wouldn't have known existed.
The one I'm going to post first is called TabMeister. It's a pretty awesome application that adds tabs to any side of your screen to allow for easy access to files/apps/etc. It also contains some awesome eyecandy, such as a burning cursor, a cursor that leaves bullet holes on your screen, and a variety of panoramas! It can be downloaded from here.
Pangea Software also has some great games, but those aren't free. They're worth it in my opinion though.
