For now it sounds like the project doesn't involve selling NFTs, which raises the question of why NFTs are required at all when the goal seems to just be to display artwork online — something the Vatican already does. Personally, until I can own the Popemobile in the metaverse, I'm not interested.
The Vatican plans a metaverse NFT gallery
A press release from metaverse developer Sensorium announced a "VR and NFT gallery" that would host art and content for the Vatican. The project will allow VR, PC, and mobile interactions, and enable people to "build unique NPCs and communicate with them". That part is a promising prospect for anyone interested in watching the Roman Catholic Church try to deal with the challenges of moderating metaverse shenanigans, and made altogether more amusing by the fact that Sensorium's current collection of example metaverse avatars are all hypersexualized, apparently covered in oil, and wear skimpy or sheer outfits apparently made from mesh, latex, and various harnesses.
