 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.
