Water Lilies by Roger Johnston. Flaming fractals differ from classic IFS by using nonlinear update functions (sinusoidal, spherical, swirl, horseshoe), using a log-density display to color pixels according to how many times they result in the process, and incorporating color based on which rule was applied to get to that point.
