Mandelbrot set

This famous fractal is generated by mapping each point c in the complex plane to a colour representing the value of n,
where n is the lowest integer for which Mod(z(n)) > 2.0, where z(0) = 0 and z(n+1) = z(n)^2 + c

Variations on the Mandelbrot set

The following fractal is created by changing the iteration formula to z(n+1) = z(n)^3 + c
