Geek built a little Mac OS X Dashboard widget (10.4.2 and later) that is an “RPG Attack Calculator”, or so I’m told. It’s up on the Apple Downloads area and available directly from the geek and dad website: Attack Calculator Widget. Pretty Geeky, but I guess that’s the point! 🙂
Donation-ware – if you like it and want him to do more, press the donate button at the above link or in the widget.
