When I started this thread one of the things in the back of my head was cultural patterning.
I am over simplifying this but ... I had a book once that demonstrated how you could tell something about the environment of a civilization by the types of lines used in their patterns. If the culture was on the plains or a desert you would see a lot of horizontal straight lines ... near water swirls .... and so on ...
So I am very happy that the CASs here do such a good job of breaking away from the modern looking stickers provided.With layering and positioning, I feel like they have been altered to feel more unique and specific to a people and a time.
