Still Waters Run Deep is an immersive and interactive experience created using Unreal Engine and optimised for Virtual Reality. It builds on the practice of sound and music therapy by incorporating binaural recordings and location-based directional audio. These elements are complemented by audio-reactive particle systems and underwater motifs. Acting as a relaxing space for self-discovery it aims to destigmatise storytelling around emotions, mental health, and neurodiversity, as well as provide a complementary resource for traditional therapy.
