 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.
