   I was puzzled by the "Of course": To me, this is not intuitively clear.   
   Is there any easy (not too technical) way to "see this"/make it   
   plausible? My gut feeling (wrongly?) said that the base should not   
   affect the randomness of a numerical pattern. "Of course" I am aware   
   (and taught to dozens of numerical beginners) that, say, 0.5 in base 10   
   has a non terminating representation in base 2, but "random" is neither   
   representation.   
      
   Pointers or simple counter-examples highly welcome!
