Julia Fractals. I rendered them in 10k resolutiom and even then it doesnt do justice to the mesmerising patterns.
They are rendered with distance functions. This particular julia fractal is one very interesting one at the Misiurewicz Point
M_23,2 = -0.77568377+0.134646737*i. It's my favourite point on the Mandelbrot Set so far.
It's lost. Probably forever.
