A proper study of the topic, with well-known fractal formulas would be interesting. I am just not interested in digging deeper today. So for now, here are a few experiments that scratch the surface of the named topic. Of course the series could be extended in the future.

The first of two flat ones.

Here are a couple with broken pieces. This could become a separate series in the future.

Metallic coloring with a low iteration fractal. Also something I want to revisit someday.
