Steve Caplin marvels at a new Saatchi Gallery exhibition which you can tour without leaving home. He highlights Amazon's disastrously translated Swedish launch, looks at the app that can tell if you have Covid-19 from your cough, is fascinated by diamonds made from the sky and reports on a patient whose leg was treated at a different hospital than hers. He was hugely impressed by the new Oculus Quest 2, bringing realistic VR gaming into the home.
