While we're big fans of Samsung's Gear VR, Google's Cardboard is still the cheapest and easiest way to get your feet wet with virtual reality. With just a piece of cardboard, velcro, a couple of lenses and your handy smartphone, you can set foot on Mars or be immersed in a Paul McCartney concert. But what about capturing VR? You'd have to cough up huge amounts of cash for a crazy GoPro setup or something much more expensive. Or maybe not, thanks to Google. The Mountain View giant has democratized virtual reality once again with a new Cardboard Camera appthat promises to turn your ordinary smartphone into a VR camera.
