For UCSF’s new hospital building MD was asked to picture the metaphysical ‘weight’ of humanity. Big data from global public health studies–birth information, physiological measurements, population density–was processed according to a proprietary algorithm that transformed the raw data into representational images. The resulting visuals–a horizon, vacationers on the beach, a cloudscape–query our world’s values, direction, and sense of cohesion as a global community.
