It's definitely true that Oculus Rift VR goggles are capable of wonderful miracles for a 90-year-old. As for normal people? We can barely keep our heads on or even stand up straight. This poor guy strapped himself to an Oculust Rift roller coaster simulation and almost destroyed the entire room trying to stay balanced. It's so good.
What the guy is seeing is a roller coaster demo made in the MTBS3D forums. I guess the moral of the story is to be like that 90-year-old woman, stay in your seat when you're going into another world. [YouTube via The Awesomer]
