I don't really understand the cardboard. Maybe I'm using it wrong. Does it provide any VR/3D feeling at all? Whenever I used it it only felt like a big zoom and the fact that you can move your head around, but I can just use my mouse wheel to zoom in and use my mouse to rotate around for almost the same effect.
