 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
