Instructions:

  I've included two versions: one for 40-column video modes, which
  gives a prettier result, and an alternative for 80-column video
  modes. Both are the same size.

  If your system starts up in 80-column mode, you can use the DOS
  command `mode con cols=40` to switch.

Description:

  The program contains a bitmap of one quadrant of the snowflake
  and it repeatedly drawns this in different rotations.

Comments:
  
  This feels like it is bigger than it needs to be, but I've had less
  time than previous years to spend on this challenge.
