I have created a score calculator for Quad Quandary. The instructions on how to use it and a link to the download can be found
here. It is written in Java so it can run on any platform.
As to the usefulness of this program, well that's debatable - I just created it because I wanted to teach myself some more Java after taking the intro computer science class at my college this past semester. Hope you enjoy it, and let me know what you think.
Attached is a screen shot of the program, running under OS X 10.4.
