The Last Call is an audiovisual installation we have created for the Czech Pavilion at EXPO 2025 Osaka. Responding to the Expo’s theme “Designing Future Society for Our Lives,” the work explores how our (in)ability to communicate shapes our collective future. The installation transforms a narrow, winding corridor into a fragmented soundscape. Directional speakers and custom LCD displays envelop visitors in shifting voices and visuals, evoking the confusion and dissonance of group video calls. As you move, the audio landscape morphs—whispers, interruptions, and anonymous monologues drift in and out, mirroring the chaos of digital communication. There’s no clear dialogue or resolution; instead, The Last Call stages a scenario where urgent messages are lost in noise, self-absorption, and performative confidence. Rather than offering answers, visitors are left with an open question: How do we deliver vital messages in a world saturated with information, distraction, and uncertainty?
