Hmmmmm Big field.. As fascinating as I find interdependence, especially symbiosis,
but somehow less visceral.
Recursion seems to be more related to 'economy' and elegant efficiency...
Reminds me of a longish joke that really needs voice and body intonation..
but here goes..
Two irishmen are sitting in a pub, Sean and Paddy..
Sean begins a thoughtful monologue..
"You know Paddy every day its the same fucking thing..
you get up in the morning..
you get dressed and brush your hair
you have some breakfast and then you go off to work..
you come home and have your dinner
then its down the pub for a pint or two and a bit of conversation..
then home to bed..
then the next day you do it all over again...
and you do this 30 to 40 years.. over and over
REPETITION...
REP-A-FUCKIN-TITION..... "
Paddy: "Sure, but your right there, Sean.. repetition! ..
....so what'll you have?
"Oh... same again thanks."

I don't want to get too far into New-Age-crystal-healing territory, not
in front of this crowd.. and I agree with Sagan about the New Superstitions
But... ;-)
Having heard about Mandlebrot as an IBM fellow, (him, not me ;-)
I was generating lots of fractal images a decade or so ago.. I'm
not a cryptanalyst or designing compression algorithms.. I just love
'the music of the spheres'.
A mathematician friend who succumbed to schizophrenia, and I
were discussing order and chaos... and touched on 'randomness'
(a metaphysical concept if ever I have encountered one)
The conversation turned to (more sci-fi) the story where
what was expected to be random radio noise from space exhibited a regularity
which turned out to be PI, encoded.... a reasonably sure and certain
sign of intelligence.
I speculated that were we to find some equally fantastic regularity imbedded in
nature, we might have an similar indicator of 'intelligence' and suggested something
like finding a perfect rectangle in the fractal images would be impressive.
I had already discovered many temple and bell like structures along the axis
if the mandlebrot set, where I expected to have the greatest chance of
symmetry.
About a week later I discovered this:
http://www.geocities.com/mild_colonial_boy/fracwindow.html
Of course, regular structures are found everywhere, crystals especially,
but this remains one of my favourite 'frames of reference'. ;-)
Apologies for the low res, I've scanned it rather than look for my
old dos diskettes (Recursive Realm I think it was) .
I might try and dig out if any one wants the Set reference points
Great for framing the thinking mans version of Desiderata
Nothing compares to a Cray real time fractal zoom!
If I could get one for the home entertainment centre I would
probably take Hallucinogens.. I'm old enough not to worry about
brain damage. ;-)

And Bush is worried about missile defence? My fear is
these critters.. or biological rust.
I think I liked the old days.. when scary things LOOKED scary.. big teeth, claws..
now we know death and danger are often invisible...
