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.
