[Alt Text: Screenshot of the game Needy Streamer Overload. A trans-colored anime girl sits center picture in front of a backdrop of BLÅHAJ as well as various other plushies, posters, and a desktop with a Windows 95 3D Maze screensaver. A single text-box reads "Whoops haha i shit myself"]
The image on the monitor is the Windows 95 3D Maze screensaver. Oh gosh I'm old.
xscreensaver also has an implementation of that maze screensaver
For some reason I was thinking of the first level in Hover! For Windows 95
"If one of those hovercraft see the player, a tone will sound, like a sonar ping, indicating they've seen the player, and will move to attack."
Oh my god, that's what that sound meant...
Edited, thanks!
