Detailed Description
Generates notes by searching for a chaotic dynamical system defined by a polynomial equation or partial differential equation using Julien C.
Sprott's Lyupanov exponent search, or by translating a known chaotic dynamical system into music, by interpreting each iteration of the system as a note. The time of the note can be represented either as the order of iteration, or as a dimension of the attractor. See Julien C. Sprott's book "Strange Attractors".
