Just a little program I made to help me while farming. I haven't tested it extensively yet, but it should work.
It's purpose? To scan the minimap and alert you when there is a mining/herbalism node near you. That way, you don't need to stare at your minimap while you farm.

I've only tested it in Leopard. May or may not work in Tiger.
I also made the fishing bot for Mac called GoneFishing.
