A festival-grade “play-to-power” zone where a butterfly-wing swing and six-bike spin disk turned visitors’ motion into clean electricity. Built from snap-together modules, the off-grid installation hosted 1 000+ play sessions in two days, generated power for about 300 phone charges, and became the event’s most-shared hashtag. By translating social-innovation themes into joyful action, it linked strangers, families and changemakers—proving kinetic fun can double as both talking point and power plant.
