How can a city create a living atmosphere through lighting that reacts to what is happening right now? Urban spaces are shaped not only by buildings and streets, but by light, mood, and movement. However, city lighting is often static and disconnected from the rhythms of everyday life. This Demola project invites students to imagine lighting as living urban art that responds in real time to the city and its people. The challenge is to explore how dynamic lighting installations can reflect the pulse of the city and its events, emotions, environmental changes, and human presence. By translating real-time signals and data such as weather, activity levels, or cultural moments into light, the city itself becomes a constantly evolving artwork. Teams will focus on artistic expression, storytelling, and citizen experience, using light to create atmosphere, provoke emotion, and strengthen a sense of belonging in public spaces. The emphasis is not on technology alone, but on meaning: how light can communicate, invite reflection, and connect people to their surroundings in subtle and beautiful ways. The outcomes may include conceptual artworks, visual narratives, spatial designs, or experiential prototypes that show how responsive lighting can transform everyday urban environments into shared, poetic experiences.
