GoKawiilChaos Computer Club's Blinkenlights turns city buildings into giant pixel displays
Project Blinkenlights, started by the Chaos Computer Club in 2001 with the Haus des Lehrers installation in Berlin, has expanded into a series of large-scale interactive light installations across three continents, including Arcade in Paris, Stereoscope in Toronto, and the newer color-capable Polychrome. The project also offers a Movie Converter tool letting anyone turn their own videos into low-resolution GIFs or WebP animations matching the installations' pixelated style.
