Jack Butcher, the artist behind the successful open edition NFT collection Checks, has announced a new project called Checks Elements. This generative art collection features physical and digital components and incorporates the motifs of earth, fire, water, and air into 152 generative art pieces that also feature Twitter checkmarks. Each piece comes with an NFT and a matching hand-finished monoprint. The collection will be auctioned at Christie's, with a portion of the proceeds donated to St. Jude's Research Hospital. The project also includes gamified elements that benefit collectors who have purchased previous works from Butcher and his creative agency, Visualize Value.
