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.
