Archive of Feelings

Archive of Feelings is the first-ever solo NFT project from multidisciplinary artist Mika Tajima, produced by PROOF × Pace Verso. The project is based on Tajima’s existing Human Synth series of large-scale installations that use a custom sentiment analysis algorithm to process text-based social media data and forecast collective emotions. With Archive of Feelings, Tajima brings Human Synth into the world of web3, using the same sentiment analysis program to visualize the averaged emotional data across 12 US regions on January 1, 2023. Each Archive of Feelings NFT will provide access to exclusive in-person events with Pace Gallery and private tours hosted by PROOF and Pace Verso. Collectors will also receive access to PROOF’s token-gated Discord server, a collector profile on, and potential access to future allowlists.

Custom sentiment algorithm


Archive of Feelings uses a custom sentiment analysis algorithm to visualize Twitter data across 12 American regions. Each unique NFT animates digital smoke that morphs in shape, color and density to communicate sentiment. The piece represents a 15-minute time segment from January 1st, 2023: highlighting both the anticipatory possibilities of the new year, and the melancholy of time passing in a tumultuous era.

PROOF will also help realize the next phase of the project at a soon-to-be-announced institution. This will be produced in Fall 2024 and manifest a living portrait of the country in the lead-up to the presidential election. Read more about Human Synth here.
