When I first fell down the CryptoArt rabbit hole, I found this epic list by obxium to be really useful.

Earlier this year I launched XERO gallery - a virtual gallery, displaying a collection of CryptoArt in the VR world of CryptoVoxels. All artwork was donated by artists and offered for sale with 0 reserve. All proceeds were donated to thewaterproject.org (minus platform fees). You can read about that in this SuperRare medium article. Visit XERO gallery in your browser here.
