The single, shared computer in our drafting class in high school (so this would’ve been mid 1990’s) had the Johnny Castaway screensaver and we spent a lot of time not drafting watching that damn thing.
I remember one for Windows 3.1 that had a load of animations involving anthropomorphic dinosaurs. The last scene had one dinosaur feeding a load of documents through a shredder and then another saying ‘Simon, where are my files’. I can’t remember the name of it though - if anyone can, please let me know! The other thing I remember about it was that the lamps in a traffic light in one scene were the wrong way around (green at the top, red at the bottom).
Windows 3.x had a CPU-based implementation of the sound card interface. I remember making it work just for this screensaver (which used basically all of the CPU resources on my 386). It sent PCM output to the PC speaker, but because it was a direct MMIO device (and because Windows 3 was cooperatively scheduled and because I had only one core) it would freeze the rest of the system while playing sound. Fun times.
I would regularly change the screen saver to the one that displayed a user-supplied string, supply something vaguely scandalous, and then use ATTRIB to make WIN.INI read-only.
Teenaged me thought it was hilarious.
You’ve reminded me that the Flying Windows screensaver used the font rendering engine to render the scaled Windows logos. Wingdings had the Windows logo in position 255, so if you hex edited the Flying Windows screensaver binary then you could make it show any of the Wingdings glyphs.
This was similarly entertaining to teenaged me.
