South Korean design team OlfactoLab claimed the One Show Gold Pencil for "Scent Canopy," transforming Seoul's real-time air quality index into immersive olfactory installations. Commissioned by environmental group Clean Skies, thirty-two transparent domes deployed in Hangang Park release pine-needle purifiers when PM2.5 exceeds 50μg/m³. During extreme pollution (>150μg/m³), mugwort incense systems activate to absorb particulate matter while generating indigo smoke patterns corresponding to contamination levels. 

Citizens pedal generator bicycles to drive mist diffusers; every five minutes of cycling triggers AR projections: ink wash spreads across traditional landscape paintings in densities mirroring pollution indexes, synchronized with bone-conduction headphones guiding breathing exercises. Environment Agency data confirmed behavioral shifts: public transport usage within 500-meter radius surged 37%, while asthma emergency calls in installation zones dropped 28%. Technical director Kim Min-ah explained, "We transmute respiratory crisis into communal healing rituals." The filtration modules have been procured by Bangkok Municipality and adapted for seasonal incense ceremonies at Kyoto Zen temples.
