did u kno that the symbols for the Playstation controller are not arbitrary? according to Teiyu Goto, the designer behind the controller, they each have meaning:
Square: Documents, Menus
X: No (this didn't catch on in the west because of the colors of the buttons, which Goto acknowledges)
I have seen O and X used as yes/good and no/bad bullet point markers in instructions for Japanese electronics and camera equipment from late 1970s onwards, although the colours on the controller also conflict with just about every other UI including other Japanese equipment (cameras, car dashboards etc)
