 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
