[18:28] A friend of mine recently bought a VR headset and controllers for VR games and we played Beat Saber the other day. First of all, this stuff is incredibly immersive. (Especially so when you have a fan pointed in your direction so you feel the wind while you're speeding down this tunnel. Really awesome.) Second, it is stunning how drab reality feels after just half an hour in VR. I can only try and imagine what something like a full on first person shooter would feel like. I hope I'll get a chance to try this out sooner or later. Really, really impressive tech.
