Experience capture. When something amazing, like a volcano eruption starts to happen, everyone in a tour group pulls out their phones together and, with a mixture of excitement, awe, and reverence starts recording the scene from slightly different angles. This would allow for full immersive three-dimensional panoramic virtual reality, three-dimensional sound image capture, and would be an amazing shared social experience to boot. It's sort of like when all of the Navi in avatar connect their nervous system-hair to the great tree to transfer Jake from one body to the other.
