feedback               
                                      
                            
                            
                                          
 feedback  is  for making the  process  a 
 whole  lot more  messy,  to introduce  a 
 fractal  in the  spice mix... things  or 
 populations  of things start to  be self 
        referential or self eating        
 (autovore...) or spiraling in or  out... 
                                          
 in  the sixties they did research in the 
 jungle and  in the sea  and  they  found 
 that feedback  does not give rise to  an 
 equilibrium.  they  were trying to prove 
 that  nature is a tame beast.  but she's 
                   not!                   
 this  may  hold  true  out  there... but 
 maybe not  in signal wizardry? depending 
 on  your  technique,  you  might  easily 
             find recurrences.
