With all of the buzz circulating about the Playstation 4 and the release of the design of its controller, I decided to design some promotinal pieces  for the PS4. The idea was to change the tradional number system used by Sony and change the would be "4" into the roman numeral for the number four (IV), then use the stucture of the roman numeral and integrate it with the commonly know button symbols used on the playstation controller.
