 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
