codeismycanvas#ArtAdventCalendar Day 4.
I started working through the book "Indra's Pearls" by David Mumford, Caroline Series, and David Wright. And by working, I mean implementing the pseudo-code in #python. It's fun when you recognize that a messy triple-nested loop algorithm in the book can be replaced by a single `itertools.product` followed by a `filter` call - which makes one appreciate the ease of coding in Python!
This is a "Theta-Schottky group" fractal inspired by Exercise 4.2 in the book.
