The self-driving safari runs as a native screensaver — the same Zig core as the browser version, drawn by a software rasterizer instead of the canvas. Grab the build for your platform below.
Right-click the downloaded file and choose Install (on Windows 11, click "Show more options" first). That opens the Screen Saver settings dialog with it already selected — set your idle timeout and you're done. Or drop it in C:\Windows\System32 to have it listed in the dropdown by name.
Test in that dialog runs it fullscreen; any key or mouse move exits. It's a self-contained 64-bit executable — no installer, no dependencies.
A dynamically-linked X11 binary — it needs libX11 and libXrender, both standard on any desktop with an X session. Make it executable and run it:
chmod +x safari-linux
./safari-linux
Controls: space pauses · ↑ / ↓ step a single frame · J jumps to the next intersection · Q or Esc quits.
