 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.
