Hey! Neat! I think it'd be cool if you could personalize the flags in some way. Like if people could tweet an image at you, and you generate a flag using their image as the seed. Where were you thinking of taking it next?
Admittedly, this has been a small side project for me. So far, I'm just adding new templates and icons so far. I'm not sure as how to actually reply to users for right now and it pretty much just runs svg generation from randomizing elements from the grammar. Another possible angle was to start naming the flags, but that requires time into essentially making a new grammar on the side.
