 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.
