I think I just may be on the right track here Richard.

Check this crap out:

However, there is a caveat. This new setup produces _two_ keys.
F0 is the formula itself, while F1 is a "unique?" offset into
it derived from the nature of the cleartext. IMVHO, F1 can be
sent across the wire because it is useless without the private
key F0. Therefore F0 would be private, and F1 public. Therefore
A transmission between Alice and Bob would go as follows:

0: Bob and Alice decide on a fractal formula F0 they both think
     is beautiful.

1: Bob wants to send a private message M to Alice.

2: Bob gets a setting S for another fractal formula F1 derived
    from F0 and encrypts M as EM with F1.

3: Bob sends EM and S across the wire to Alice.

4: Alice uses F0 and S to gain the fractal F1.

5: Alice uses F1 to decrypt EM into M.

6: Alice reads the M.

This would create a unique fractal based on the characters in
the cleartext. Well, do you think this might be good enough to
post over in sci.crypt Richard?

I am a bit nervous.

FWIW, here is a sample of the output:
________________________________________
original  = Christopher
encrypted = \a\R8<d95Rl
decrypted = Christopher


original  = christopher
encrypted = zg:~0\:`Mhv
decrypted = christopher


original  = ChristopheR
encrypted = !'`O0dHG0P=
decrypted = ChristopheR
________________________________________


This is MUCH better than it was before.

Thank you all for the much appreciated comments, sage advice.
