I coded something similar a loooong time ago (long since lost the code) except that it had a hot-or-not type of grading system so the user would be shown each variation one a time, then user simply clicks on a rating for how much they like it on a scale of 0 - 10 and then they see the next variation. Of course the challenge is to seed it with meaningful font, layout, and color scheme templates otherwise the user gets bored slogging through hideous variants with purple fonts and lime green backgrounds. I hesitate to even mention it because some jerk will run off and patent it, but the real killer app of this kind guided design is architecture design software. Imagine a screen that simply shows you 4 possible variants of architectural plan, you choose just the ones you like, and the software cross-breeds the preferred designs and shows you 4 other variants and so on. People who don't know a damn thing about architecture could still use the software because they only need to point at what they like, and anyone can do that.
