On: Does anybody know this fractal? (2012)

The flower patterns remind me of Smith charts. https://www.antenna-theory.com/m/tutorial/smith/chart.php

Since smith charts are made by mapping the complex plane (grid) to another complex plane via a Mobius transformation Z->(Z-1)/(Z+1), maybe that’s what’s going on here too. The inverse certainly produces a grid again.
