Posted in memoriam of Benoit Mandelbrot: a beautiful deep zoom of the Set he discovered.
Zoom sequence: biggest spike minibrot -> triple seahorse valley -> seahorse -> spiral -> filament -> seahorse Julia jewel -> minibrot at center -> spike -> zoom quite a while at tip of spike (there are alternating bands of seahorse-stuff and nearly empty space with a few filaments wrapping it like dwell bands) -> zoom into a seahorse-stuff band just off tip -> filament -> seahorse Julia jewel -> linear Julia jewel at center -> minibrot at center -> zoom into seahorse-stuff some ways to the side of the minibrot, near its backside but off the symmetry line by a ways -> Julia jewel sequence -> zooming at center leads eventually to this.
I started this one before inventing the wave-summing coloring trick, so it uses two layers, one for a high frequency brightness modulation to bring out all the tiny filaments and one for the color gradient. The presence of a second layer, combined with aggressive antialiasing, made this a very long calculation.
