Sarah Friend launches Off, an NFT project that is artist edition, artwork, and multiplayer game all at once. 255 collectibles, each the exact pixel dimension of various computer, smartphone, and tablet screens, contain both a public and a secret image.

With a majority of key shards required to decrypt the hidden sentences, the essay is revealed only if enough collectors are willing to share their images. “Will you choose to cooperate or defect?”
