Partial Victory in Public Interest Project
/There's still a lot to do on just this desktop web app (adding a slider for number of months of interest computed, labels, cleaning up CSS, responsive), but broke through some JavaScript/JQuery issues and it's functional so far.

The live version of this is here.
Once I add the slider (and get it working), then comes: changing it all to JQuery Mobile, customizing the styling and theme (are those substantially different terms?), and starting to learn Phone Gap.
The ultimate goal: This will be part of a public-good project that offers mobile phone users easy tools for visualizing how much each purchase will cost when credit card interest is factored in, for helping users learn how to pay down credit card debt, and about credit card terms and conditions.
