It’s nothing special with this ordinary spiral from the border of the Mandelbrot set. I just love it an how the filaments belonging to the 16-armed star collapses into infinite emptiness in its very center In fact infinite empiness and infinite indiviual fullness are what builds up the filaments in the mandelbrot set See the article 14) Infinite Emptiness - Infinite Individual Fullness (What constitutes the filaments) in my Chaotic series of fractal articles [link]
