Fractal flame

Fractal flames are a member of the iterated function system class of fractals created by Scott Draves in 1992.

Fractal flames differ from ordinary iterated function systems in three ways:

* Nonlinear functions instead of affine transforms.
* Log-density display instead of linear or binary (a form of tone mapping)
* Color by structure instead of monochrome or by density.

The tone mapping and coloring expose and preserve as much of the information content of the fractal as possible. Preserving information maximizes aesthetics.
