a(virtual) reality

Virtual reality. Seems contradictory and it’s true that I haven’t paid much attention to it. So I asked myself today, what exactly is it ? I know that there are headsets, programming and video games. But there is a lot more. Movies, 3D simulators, media, hobbies, medicine, education, health and more can be involved. So off course I went down that rabbit hole and found things like google cardboard, unity, sketch and various articles on medium. Take a look and see if anything tweeks your imagination.
