Festa do Largo is a three-day neighbourhood festival with music, food and a market on one square. Its audience had moved to phones, but the festival still designed for paper first and resized for screens at the last minute, so nothing moved and nothing matched. The organisers wanted one idea that worked on a lamp-post and in a story at the same time.

We designed a single shape — a blue and orange form that folds like a paper fan — and animated it before we printed it. The title loop, the posters, the wristbands and the stage screens all came from the same file, so print stills are frames from the motion. We built a template so volunteers could post daily updates without breaking it.

The title loop passed 1.2 million views before the first night, and the festival's followers grew by a third in a month. Volunteers posted every day from the template without a designer. The shape now returns each year in a new colour pair, and the city borrowed it for its own summer programme. Sponsors now ask for the loop before the poster.
