 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.
