Leaning into notions of immateriality and the technological sublime, “Digital Art Waves” opens in Paris. Featuring artists including Kika Nicolela, Manfred Mohr, Quayola, and Nicolas Sassoon, whose contributions range from prints on paper and metal to video and NFTs. Sabrina Ratté, for example, reconstitutes her reflection-heavy 2016 CGI video piece Wintergarden, which “straddles the line between abstract architecture and an enclosed garden,” as an NFT (image).
