Post by: element90 on July 03, 2013, 11:25:37 AM
A sequence of zooms leading to a Mandelbrot island, not in the standard Mandelbrot set.

Formula:

z = transform(z)
z = alpha(beta*z^gamma + delta*z^epsilon)

initial z = 1
alpha = location in the complex plane
beta = -2.5
gamma = -2
delta = 1
epsilon = -5

Two transform sets:

A - empty
B - inverse fold out (circle diameter = 2.5)

Transform sequence AB i.e. the transform sets are applied on alternate iterations.

Colour method is absolute log of exponential inverse change sum
