My "family" has 8 children so far. I think I could add a few more "offsprings". It was fun to go through the options. Initially, I did not think I could come up with more than 3-4 because this is an abstract pattern, but things worked out. 

I'd like to try adding some gold or silver texture to the monochromatic versions - but only to some elements. The procedure in the course adds the texture to all the elements and I am wondering what would be the way to apply it selectively.
