LandmarkCanvas: Ephemeral Geo-Fenced Collaboration
Design a digital 'graffiti' platform where users can only post or view content if they are within 100 meters of a specific physical landmark. Each landmark has a shared canvas that resets every 24 hours. The experience must be real-time; if one user 'paints,' others at that landmark should see it immediately.
