         | 1998. It looks nothing at all like hand-pixeled art.

           | the purple/pink pattern on the bottom left corgi).

       | Now you can generate cheezy NFT art from public domain images.

         | None of the samples are appealing (except for perhaps that one
         | with palm trees).
