 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

 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

             Find Recurrences.
