I put together a nostalgic theme, in the style of 1980s monitors. It uses the same font that the Hercules graphics adapter had. Try it out by choosing "Hercules 1982" at https://piefed.social/user/settings.
You can toggle between amber and green by using the dark or light mode icons in the header.
I'm happy with the font and how the amber version looks but I found it very difficult to get the right shade of green. Modern monitors do colour so differently.
If anyone would like to make their own themes or improve the existing ones, here is a quick intro - https://join.piefed.social/2024/02/07/changing-piefeds-appearance-with-themes/
Totally awesome!
