Sony owns PlayStation and Ghostbusters, so why not combine the two? This is a very simple design: the back of the case is molded in red, the shoulder buttons are translucent blue for the sirens, and lastly the USB cable is royal blue to match the hose that hangs on the car.
Thought about making the OPTIONS and SHARE buttons yellow, but they are probably injection molded with the rest of the buttons (whereas the shoulder buttons are a different color). I also wanted to add chrome accents, but that would be difficult too.
Maybe Sony could make these as a promo product for the new movie? A matching console could be done as well (if there’s interest I could add a mockup here), but without a new tie-in game that would be unlikely.
