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.
