There is an increase in VR art galleries, and online exhibitions, over lockdown. In the Metaverse, Omniverse, see below.
Here’s my VR gallery (with coder Christian) from my design and build web studio Twin Media (London) back in 1995. VRML was a web based 3D renderer with a simple mark-up language, superseded by X3D.
Search for Metaverse, Cryptovoxels, etc. Second Life is still around. These sites have always had usability issues and are just a bit clunky. There are lots of 3D world-building games such as Minecraft, Fortnite and Roblox, and of course Sim City. Nvidia has an Omniverse. Facebook are really into this via VR.
