I did not get motion sickness when I demoed Sony's new and improved Project Morpheus VR headset at GDC this week in San Francisco. And that's saying a lot considering my sweaty outcome at a private E3 demo last year. But I did get somewhat hurt while using it. Blame it on the shark. I banged my head into a wall while whimpering and trying to avoid the jaws of a menacing virtual version of, well, JAWS. It's proof that compelling VR is powerful; powerful enough to send you slamming into nearby walls with a smile plastered on your face.
