Finally fixed those 404s from browsers looking for favicon.ico on this blog.

  1. Google image search for images where “reuse with modification” is allowed.

  2. Found this high-quality lab mouse SVG image.

  3. Opened it in GNU Image Manipulation Program, posterized, cropped to a square. Kept the transparent background.

  4. Just went to realfavicongenerator.net and did what it says, and added the resulting images and markup to the site.

That’s about it. Now there’s a little mouse in the browser tab (and it should do the right thing with the icons if someone pins it to their home screen on mobile.)
