And the funny thing is that there's no app in Steam Right now to watch 360 videos from youtube on Vive. Google, you have great Tilt Brush. And no Youtube.

Can't you watch YouTube 360 videos in the round with virtual desktop software? Something like BigScreen, I think, should work (haven't used a Vive in a couple months).

Edit: cursory googling suggests the BigScreen devs, as one data point, intentionally don't support 360 videos. Personally I agree that's the right call (360 videos are not good experiences IMO), but seems to be an odd omission for their software. Still, I'd be surprised if YouTube 360 is totally inaccessible.

it's kinda accessible via other players when you download clip. But downloading clips is per se not good. 360 is quite good then - I don't have any issues, especially, if it's at least 4K
