I love these tiles. Tiny and repetitive designs and patterns that are put together with certain complexity and harmony, and all the components, while being different, have a single unity.
These designs are mostly used in architecture. In Persian architecture, they are called "motifs". And it is more common in Middle Eastern countries such as Iran, Turkey, Afghanistan, Syria, Morocco, Egypt, and others.
I have made more than 228 procedural patterns that you can see: https://www.artstation.com/a/260002
