I tried implementing search for "nice" random iterated function systems (IFS) using the Lyapunov exponent (and a generalisation where I histogram the exponents instead of just using the average), unfortunately with no good results: I couldn't find a way to characterise / filter out the crappy attractors from interesting ones.
