Admittedly without yet reading but just looking at the pictures, I'd love to see examples of where it creates patterns of patterns. Sort of like the biomes in Minecraft: one pattern to draw out where the biomes are, one to fill them in with content. Could it be made to do patterns of patterns of patterns?

If this were used to create level design where the local view is several iterations deep of patterns of patterns but not yet all the way to the bottom, I guess a fractal, that would be a trip.

Awesome work!
