I suspect this isn't the revisitation you meant...

.      In most American and British Braille systems, the pattern (1-3-5) is an o.

  .
.
  .    With a 180° turn, the pattern becomes (2-4-6) in the Braille system and is the contraction ow or an opening bracket [.

.   .
  .     With a 90° turn 'clockwise', the pattern may represent the v in the New York Point system where a cell is two rows instead of columns.

  .
.   .    With a 90° turn 'counter-clockwise' the pattern may represent the y in the New York Point system.  

.  .
    .    With an approximate 45° 'counter-clockwise' turn, the three dots might be seen as the cross product symbol × in Nemeth code.

Or, with keeping the dots perpendicular with 45°, 135°, 215° and 305° 'counter-clockwise' turns, the three dots may appear as one of the following in a Braille system:
. . (1-4-5):  d    4  do   
  . (2-5-6):  . ?  4  dis 

. . (1-2-4):  f    6  from
.   (2-3-5):  !    6  to       

.   (1-2-5):  h    8  have
. . (2-3-6):  " ?  8  his  

  . (2-4-5):  j c  0  just/Jesus 
. . (3-5-6):  " :  0  was
