I briefly checked out the "Museum Of Other Realities" thing https://www.roadtovr.com/museum-other-realities-free-weekend-2021

it is pretty huge, ~20GB download of weird modern art. It is multiplayer, there's some party system where you can talk with people in your party and also see other randos moving around like ghosts. movement is teleport-only, though you can hold down the A button to (really) slowly drift in the direction your controller is facing. You can grab "drinks" from behind your shoulders to get bigger or smaller, which is a neat touch, and there's also a 3d marker to draw stuff with.

I'm going to do a proper runthrough of the museum this Thursday, at 9PM EDT, if you'd like to join me. 

It's all a single instance AFAICT, so I'll just post my name on Thursday and you can find me on the map, join the party, and shitpost about modern "art". It's like 20GB so remember to download in advance too.
