One of my favourite little zooms from the earlier Mandelbrot zooms on Maths Town. At about 1:40 the zoom drops into a mini-Mandelbrot and begins some very dense spirals. The spiral patterns then repeat periodically at higher symmetry. A Mandelbrot zoom that was requested by shoenborg.
This video is a good example of how Mandelbrot patterns repeat at a higher rotational symmetry, because the dense spirals are very obvious. In the screenshots below I have included several views of the patters repeating at higher symmetry.
