Check out this 360° video made as a demo by Samsung. If your internet speed can handle it, I recommend watching it in the full 4K resolution. It will be pretty amazing to hook up the Oculus Rift to video like this and get the fully immersive experience.
Use the ‘W, A, S, D’ keys to control direction on a computer.
Use the + and – keys to zoom.
I think you have to move your phone around if you are watching on mobile. But again, the real experience is to watch this type of video with an immersive virtual reality headset. FYI: you can cheaply get this experience with something like Google Cardboard and your mobile phone.
