 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.
