This article examines “De Tripas Corazón,” a project merging generative art with scientific data to visualize the gut-brain axis and emotional states. The project aims to use generative art as an innovative way to represent technical and scientific data to an audience. Dynamic visual and auditory portraits were created with Touchdesigner software and a Muse headband for real-time interaction; electroencephalography and DNA sequencing of colonic microbiota data were used to construct the portraits. Ultimately, this article highlights the versatility of generative art presenting physiological data as an immersive aesthetic experience.
