Watch a cancer operation at any angle via Google Cardboard

St. Bartholomew's Hospital in London next month will live-stream an operation on a cancer patient in 360-degree video so that it can be viewed by anyone in the world with a virtual-reality headset. "We've got to think about this because this is expensive medicine," said Ahmed. "Medical companies take you on the road. Actually do you need to? Why not give people headsets? Teach people remotely. They don't have to be barricaded."
