Earlier this year I was treated to my best-ever VR experience when I visited the Virtual Human Interaction Lab at Stanford. I put on a HTC Vive, and by moving my arms in certain ways I got to free-fly around a computer-generated city, just like Superman (or woman). Although it was just a demo and the graphics were nothing that special, I felt I could have explored that virtual city forever, regardless of the fact I am actually afraid of heights.
