A hundred years after Gaudí learned to build from nature, media facades have lost their origin. They sell, they glare, they ignore the people walking past. In one day, and in the age of AI, students of Chung-Ang University's Graduate School of Virtual Convergence design building skins that give back to the city and to nature. Working in teams with the Origin8 method, they choose a real place in Seoul, define a real need, and build a living media facade concept with mentors beside them all day, closing with a pitch to a jury. Selected work is exhibited publicly at a gallery at COEX in August. Part of the Back to the Origins campaign, marking 100 years of Antoni Gaudí (1926–2026).
