Experience
Vestigia: Owner
Kulturformidling – cultural mediation. Vestigia builds the things that carry a story to the people it belongs to: audio guides, information panels, augmented reality, and interactive installations for museums and cultural institutions.
The work spans storytelling, composition, sound production, and software development, on the conviction that the medium should serve the story rather than the other way around – and that a good story can stand being told quietly.
