do you know that you can watch in 3d without glasses in the Nintendo dsl using a simple trick that gives the image a little depth of view. the trick is simple your going to watch the upper screen of the ds from the bottom screen, confusing isn't it? this is only possible if the bottom screen is black or blank. when your watching in moonshell if you touch the bottom screen and holds it down. the bottom screen will fades slowly till it goes black. when that happens we can do the trick. what we really need to do is to make the image from the upper screen of the ds reflect on the bottom screen, so you need to half close your ds till you see the upper screen reflected on the bottom screen perfectly when that happens it will produce two offset images that gives a slight 3d effect. you can see in the picture that my ds is upside down and the upper screen is reflected on the touch screen.
That's not 3D. It's just a double image cause by the fact that the touch screen has two layers in it. There's not even any 3D information built into the video you're watching.
