Oculus is showing off the next version of its Rift virtual reality gaming goggles by appointment only. In a back corner of the exhibition hall at this year’s Siggraph conference in Anaheim sits a 10×10 white box with a door, a temporary private office used at trade shows. To knock on the flimsy aluminum door causes the entire booth to rattle. “I was told to ask for Joe,” I said when someone opened the door. “This must be what entering a speakeasy during Prohibition was like,” I thought to myself.
