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.
