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.
