A pair of non-identical twins

A complex number x + i y can be plotted in a complex plain where the x coordinate is the real axis and the y coordinate the imaginary.

Let’s consider the following iteration:

z_{n+1} = z_{n}^2 + c\quad\quad\quad(1)

where z, c are complex numbers.

If (1) are started at z_0 = 0 for various values of c and plotted in c-space, we have the Mandelbrot set:

When c is held fixed and points generated by (1) are plotted in z-space, the result is the Julia set:
