Arnis is a geospatial data pipeline in Rust that fetches OpenStreetMap and elevation data, then generates Minecraft worlds. Real technical work: coordinate transformation, terrain mesh generation from raster data, building footprint vectorization. The science score is moderate because it's engineering-solid but not novel algorithmically—it's applying known GIS techniques to Minecraft generation. High signal: solves an actual problem (generating believable real-world Minecraft maps) and ships ...
