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.
