not my first metaversal construction, either.

ol' wakey also owns some historic buildings and units in Aether City, Ethereum's first on-chain metaverse (launched Mar '18).

No longer being developed, but worth a gander if only for the historicity of it all (NFTs didn't formally exist yet, ICO mania was unwinding, etc).

Ooh is there anything inside the buildings?

Another 3D NFT gallery experience? I... don't know of any, actually.

Aether and Cyber are it, afaik.

There are other NFT gallery services (ie, Gallery), but not with immersive environments.

Ah, so its not as streamlined as oncyber or ... what was the other one?

kinda sorta. owning a building entitles you to NFT gallery templates, rather like Cyber but minimalist.

the idea being that the gallery is in the building, but there's no visual congruity; no view to the street and no entrance from the outside.
