I don't know if these links still work, but try them for more info:

Also search on "oscillateur chaotique" for a schematic (in French) of a
simple VC Chua circuit. I don't have the URL because I printed it via
Babelfish.

IBM researchers did some work on the odd effects of coupling these
circuits... kinda mixing a little Theremin-like technology into the chaos.
Look for a paper called "Synchronization in Arrays of Chaotic Circuits
Coupled via Dynamic Coupling Elements."

There are companies who are supposedly making a chip version of these
oscillators because Chaos is being studied for cryptological purposes. I
don't know what they cost or if they can be adapted for audio (or if it's
even worth it since the circuitry is so minimal).


A lot of this can sound like greek if you haven't been exposed to a little
Chaos in your life (read James Gleick's (sp?) book).

Also search for a paper by Michael Peter Kennedy called "Robust Op Amp
Realization of Chua's Circuit"


PS: I was told by an Asian friend that "Chua" is pronounced "Koo" but I
don't know that for a fact.
