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.
