Open-source vector GIS poster studio — design & export museum-grade 4K map wall art from OpenStreetMap vector tiles.
Type any place and download it as a high-resolution map print — satellite, neon, blueprint or line drawing, up to 6000px per side. Pure client-side JS on GitHub Pages: no backend, no build step, no API keys. Built with Claude Code.
Living map wallpapers spanning three monitors — five true-vector OpenStreetMap posters built from OpenFreeMap tiles, animated in one HTML page with road traffic pulses, solar-driven palette drift, idle-state crossfades and live Open-Meteo weather, deployed to Lively Wallpaper in span mode
