Collective Blooms is an interactive experience that turns Pak Khlong Talat, Bangkok's largest flower market, into a garden grown by the public. Visitors find hidden digital seeds through a no-download web app, personalize them as paper seeds, then plant them through projection mapping on the Grand Postal Building's facade. As each seed is planted, it grows into a unique digital flower, and together they bloom into a shared, ever-changing garden on the building.
