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.
