chaotic function generator: Chua's circuit

[Ray Peck]

Has anyone here tried "Chua's circuit", which is a chaotic function
generator?  See

Seems like it would be a winning control module.  They have simulation
source in 100k+ of BASIC (including fancy plotting stuff).  It would
probably be worthwhile writing the core in Csound to check it out.
