Wow...didn't expect so many replies. I wrote this little
multiplexed post, hope not to break any netiquette here.

Ian,

  > Chaos is *not* random.

This is a key answer, thanks. Having confussion with these terms
is what lead me to spent a good time on Google. I would like to
see your study on chaos when ready for public. (my ears/eyes open)

Philippe, Veronica, Paul,

I'm on path now, even if this mean 'then I must walk' (ouch..)
thanks.

Drew,
  > you could try "turbulent mirror" by john briggs and f. david peat.

I did check the brief at Amazon and if it's what I think (chaos
for dummies) it's the perfect book for me :) thanks.
Actually I don't know who can be indifferent to that title.
(Turbulent Mirror... Wow. Why it didn't occured to me?)

I remember when was a kid I used to play with my father's amp and a
battery cell, an old and completely corroded one. I remember the amp
making very funny noises with that "patch" (battery to line input through
bare wires). With "funny" I mean something different from white noise or
clicks and pops, but a noise close to glorps.mp3 (link provided by
John Mahoney), of course without the extra filtering and echo. It was
repeatable but only with batteries in really poor conditions, only those
nearly disintegration preduced the richiest sounds.
I read somewhere about sound generation using chemicals, I think it
was in Mr Nyle Steiner's website but not sure if it have any relation
to chaos.
Could the battery+amp be one of those non-FB systems? or is it the kid
that performs the loop?


To all people in the thread,

It is much clear now. A lot of urls to follow, and surely I will need
some time to digest all this. Thanks to everyone.
