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.
