It was inevitable that my purchase of a Ricoh Theta S 360° camera would spur me on to buy more tech. The big hand syndrome, where handheld pictures and video have an out-of proportion hand holding nothing (the camera having removed itself from the picture) was easily fixed by a selfie-stick/monopod.
But it also led me to play with Google Cardboard, which is a deliberately cheap design for a Virtual Reality headset. In particular, video taken with the Theta and uploaded to YouTube can be viewed using Google Cardboard, and as you move your head, the frame of view moves accordingly. It is an amazing immersive effect, even with the crudest resolution of video.
