The article mentioned a laser pointer, was this to actually interface with the PS, or just as a guide to see where you are pointing. Either way it is retarded, if the laser is to control it, then it wouldnt be practical if you wanted to rest it in your lap while you play or something (still using the motion sensor). If the laser is used only as a guide for the player, it would be pointless because a sight can easily be programmed onto the screen to serve the same purpose.
