 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
