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.
