Remember that Facebook built a wacky 360-degree camera to record immersive video?
Well, now it s shot its first film, which allows you to explore New York s Grand Central Terminal.
Mark Zuckerberg posted the video to Facebook overnight, calling it a preview of what a full-length virtual reality movie will feel like.
Especially if you re a fan of train stations!
You don t need a VR headset to watch the video, but it does work better on a phone than a PC, because you can wave your handset around like a loon to see what s happening around you.
