Patterns in the ASCII
---------------------

This is what ASCII looks like if we leave out the alphabet
and special characters.

    0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F
00
10
20     !  "  #  $  %  &  '  (  )  *  +  ,  -  .  /
30  0  1  2  3  4  5  6  7  8  9  :  ;  <  =  >  ?
40  @
50                                   [  \  ]  ^  _
60  `
70                                   {  |  }  ~


Looks a lot like a keyboard layout, doesn't it?
