I made this a few years ago, to compare the size of the entire screen on an original 128k Mac with the size of the Safari icon on modern macOS. Enjoy!
@thomasareed why is the red tip off center of the dial marker? 😫
@chrisvest @thomasareed relax the gray side is also of center... but not in a way you would expect it if it's just rotated around the center. So the entire needle is slightly of center to the compass frame. 🙃
