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.
