 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
