My circles are broad as well as narrow, depending on need. 2=2
  is typically narrowly circular. Yet it can be broadly circular
  as art, a metaphorical partial imperfect mirroring across the
  diagonal encompassing a perfectly hewn = with imperfectly
  diagonally hewn 2s, allowing for the two halves shown together
  as a metaphor for chirality and why the Universe exists and
  is/cannot be in perfect balance and harmony. So, it depends.
