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
