Today I learned that there's a version of XScreenSaver for iOS. I haven't used XScreenSaver in years; probably decades at this point. Not because I don't like it or anything; it's just because I've not had a GNU/Linux desktop machine in that long. But the chance to install the app on my phone and scroll through all the different graphics demos is too good to pass up.
I noticed this because I saw xscreensaver-official/xscreensaver pop up in my feed on GitHub.
I, of course, added a star to the repo because the owner asked nicely.
Now I might have to throw the Mac version on my Macs.
Or, you know, turn one of my older MacBooks into a Linux laptop and use it there (something I keep meaning to do).
