 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.
