The Mrs Fractal: Mirror, Rotate, Scale (2025)

http://www.4rknova.com/assets/img/post/20250622-mrs_fractal/cover.png
Fractal rendering is usually introduced with Mandelbrot or Julia sets, but those are not the only way to generate rich self-similar structure. The MRS fractal is a small iterative system based on three geometric operations:\[p_{n+1} = s \cdot R\left(M\left(p_n\right)\right) - o\] This loop folds space back on itself, then expands it. Repeating that process creates nested structure at many scales.
