An interactive 3D journey inside the brain, visualizing how sound frequencies trigger physical reactions. The challenge was turning the invisible, hearing as a bodily sense, into an immersive Unreal Engine experience. We chose the ear as focus, blending sound design with synesthesia-inspired visuals: organic forms that pulse and morph in real-time as you 'walk' through neural landscapes and interact with the controler producing the frecuencies, you are the sound. Result: A sensorial world where as the sound, you literally reshapes matter. Role: Concept Development, 3D Modeling & Post-Production. Team: Pol Tarrés, Nael Lamaison, Paula Palacio, Carla Mártinez.
