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.
