Prediction: when somebody does something as pretty as this using SVG, or Canvas, a landslide of people will give up their previous generation browser. It doesn't have to be a plugin for Mint or Google Analytics, though it would certainly help.
The best thing about this is that I'm fairly sure this can already be done today. All it takes is the hard work of a good graphics artist with a knack for vector graphics, and perhaps some minor understanding of programming, or a programmer with the patience and follow-through to mimic the design closely enough in code, or parametrized vector paths. It's an interesting challenge, isn't it?
You would have Ajaxian beating down your door before you realized what happened, too. :-)
