I wrote the script that provides the GOES NavSum [1] and it pretty much just builds a standardized text file and drops it in the folder. The neat thing is that this makes it really easy to programmatically scrape and parse the data.
I wrote a personal script at one point that would download the GOES-EAST CONUS image and both EAST and WEST full disk images and composite them into a wallpaper. At one point my server had 500GB of archived GOES imagery. I liked to joke with my former coworkers that I could report image anomalies before they notice because my desktop wallpaper would change every 10 minutes.
I still have the script somewhere. I should throw an LLM at it and see if I can't sand off a few rough edges.
I've got about 2.5 years worth of that imagery if someone knows a good way to do this on a budget.
Could have stopped there for 99% of websites
Actually, I used to have a live-updating website AS MY BACKGROUND. Windows 98 and Me, website used AJAX and Comet to make it happen.
You used to be able to set websites as your desktop background.
This admin gutted both NOAAs budget and workforce so a website redesign is probably low priority at the moment.
Edit: I think actually it's a screenshot of a screenshot even, and this appears to be the entire design of spaceweather.gov. What in the holy heck is going on there? This has to be a top 10 worst website designs of all time.
