 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
