Organized by the NFT platform Verse, American generative artist John Provencher presents two playful net.art-inspired bodies of work at Cromwell Place in London. The first, over-time (2023), pays homage to the blocky visual language of Alexei Shulgin’s Form Art (1997) via dithered animations of twisting Lissajous curves, while the second, HAHA (2023, image), sardonically “visualizes and plays on the transactional nature of NFTs” by spewing an endless stream of “generative receipts” from a thermal printer.
