Show HN: Codebase Posters – turn any Git repo into generative poster art

Codebase Posters is a tool that transforms any Git repository's commit history into generative poster art by running a single command (`npx codebase-posters`) that generates 18 unique, printable posters in your browser. The tool visualizes coding patterns through abstract designs—blue strokes represent code additions, green represents deletions, and dots mark significant commits—all processed locally without uploads or telemetry. Each poster is deterministic and can be saved as high-resolution images (3600×4800 px) suitable for printing and display.
