To commemorate the 20th anniversary of the Tokyo International Forum, we created spatial video production for the limited-time “Light Aquarium” event. Using the walls as a giant screen, we crafted an atmospheric world with fantastical underwater imagery. By sensing the dolphins’ positions with infrared sensors, we also incorporated interaction that changed the images projected on the walls. Processing everything in real time created a presentation that felt even more seamlessly integrated with the space. By adding story-driven visual direction to the transitions between scenes, we aimed to create a highly entertaining experience.
