Pick a place, a theme, and a print layout — export a poster-quality OSM map. Ships a curated catalog of 758 boundary-aware places across six Vietnamese cities, each clipped to its real administrative outline, plus free-pan for anywhere else. WYSIWYG A0→A5 preview, Vietnamese-aware typography, headless render CLI.

Shows: taking raw OSM all the way to a self-serve product — pipeline, cartography, front-end. code

Every time a bus, tram, or train reaches a stop, a ripple spreads along the streets a rider could walk in three minutes. Where ripples overlap, the city's pulse brightens. Five cities — Helsinki, Amsterdam, Berlin, Vienna and Zürich — from the same city-agnostic pipeline.

Shows: baked physics + WebGL2 playback, and an ingest that absorbs five national feeds — each with its own quirks — behind one schema. code

Where place-name morphemes cluster across Finland, Sweden, and Vietnam — a glowing scrollytelling map. Finland names the land it sees; Vietnam names the order it imposes. Long — dragon, prosperity — lights up 81 places on its own.

Shows: turning bilingual NLP into a story you can read on a map. code
