Feedback               
                                      
                            
                            
                                          
 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.
