You have to have content to show this off. If your wanting to show this technology off you have to generate images that have two seperate perspectives. You can either go film something like this, if you have ever seen the camera setup for IMAX 3D with the two big cameras on a rod you get an idea of what a pain this is to do, or you can generate it synthetically. Sony though can just have the PS3 output two slightly offset images of the same thing by making slight modifications to their programs -- and they look excellent as they have already done all the work to make a great graphics and artwork for their games.
If you want to test how this works it is easy. Get something with an LCD screen in it, small TV if you have one, and some polaroid sunglasses. Put the glasses on and spin the screen, at some angle the display will vanish. All they are doing is making a screen that does this but at two angles. It is not really a new idea, you have been able to do this at theatres for a long time but as is usual this is about migrating the technology home.
