Binary Clock

[Mekire]

The one thing I notice is the lack of row 5 (0), so midnight 00:00:00 won't show up.

Midnight should work just fine.  It will be all zeros.  

Anyway, latest version.  Flickering fixed; update speed increased so we don't miss some seconds (as could happen before); deciseconds added; some overall simplifications:

   for bit, cursor in zip(binary, cursors):
       color = ON if int(bit) else OFF
       print("{}{}{}".format(color, cursor, bit))

   cursor.hide()

   start_time = time.clock()
   while time.clock() - start_time < seconds:
       time_digits = map(int, datetime.now().strftime("%H%M%S%f"))      
       for digit, column in zip(time_digits, COLUMN_POSITIONS):
           render(digit, get_cursor_locations(column))
       time.sleep(UPDATE_SPEED)
