 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 
            Find Recurrences.
