I am positively itching to show you this project. It's like...fleas of excitement.
I can tell you this much: Its name is "Chutes, and also Ladders." It involves charts, but relatively intuitive and non-scary charts. And it will be available very soon as part of the KnitCulture Studio Club, which looks like a darned awesome club to be in. (It will be released for non-members a month or two later.)
Also, Sarah tested it and gave it her official seal of approval, so that oughta count for something ;-)
