 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.
