Back before I discovered Linux, I still had a bunch of computers in my room. Since I hadn't yet discovered Linux, I had a bunch of Windows computers. Therefore I saw a lot of classic screensavers all the time (and also my room was very warm).

Moreso than that, though, one need only understand the concept of a screensaver and maybe watch a few minutes of this to intuit that there is no end and never will be.

I liked the pipe one. It cleaned itself up periodically and, since there was no character on display - either via first person perspective or seeing someone build pipes - no one was desperate or trapped. However, the starfield was always my favorite. It spoke of adventure. The idea of having an occupiable spaceship was enough of an idea of home to not stress me out.

I also had one that came on the Duke Nukem 3d CD (though it didn't come on mine, I had to email and ask). It depicted Duke's enemies rather messily falling from the sky until they filled up the screen. When I learned that was a thing I was of the perfect age to appreciate it.

Nowadays I just use the power management settings. No screen saver.
