I have created the repo, some basic JavaScript to keep track of the hour of day (to have a different display for day and night) and a video of the moon. However, the video is quite shaky, and there isn’t a really good way to implement this for the screensaver, so I am considering switching to an image of a moon, which I will then position using JavaScript, and the time of day. I can do the same with the sun. I will attempt this, and I will try using my new-found parabola skills learnt at school to write quadratic formulas to get the rising and falling of the moon right, especially for different scale screens.
