The next step toward realism and applicability is taken when the extended Weierstrass function is randomized. The simplest and most intrinsic method consists in multiplying its Fourier coefficients by independent complex Gaussian factors of zero mean and unit variance. The real and imaginary parts of the result deserve to be called Weierstrass(modified)-Gauss functions. In several ways, they are approximate fractional Brown functions.

The first self-inverse fractals were introduced in the 1880's by Henri Poincarré and Felix Klein, not long after the discovery by Weierstrass of continuous but not differentiable function, roughly at the same time as the Cantor sets, and well before the Peano and Koch curves and their scaling kin.
