 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

 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
