VR turned me into a movie character -- a tiny, bright yellow firefly. But here's the best part: I got to experience it with someone next to me, both literally and virtually, in a dark room with headsets strapped to our heads. For Oculus Story Studio, arguably the Pixar of virtual reality, this is the first step in making the medium more social. And it's using its short film Lost, introduced earlier this year at Sundance, as a test bed. Still, whether we're talking about a cute movie or a fun game, most VR activities so far have one thing in common: They're solitary experiences. Oculus wants to change that.
