Were you aware that the blockchain-based virtual world Cryptovoxels has a flourishing art scene?
More and more often, I see announcements about art galleries and installations in Cryptovoxels, both regular art and blockchain art (the production of which is described at length in this article). Good sources of information about openings and events are the official Cryptovoxels Twitter and Discord channels.
If you are looking for galleries to explore, I can suggest no better place to start than Listed: Blockchain Art Galleries on Cryptovoxels.com, a directory of approximately forty galleries to visit. Or you can take the new Cryptovoxels Art Tour (CAT), which has an official guide book to approximately 30 art galleries. You can hop directly into each gallery from the guide book!
