 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
