Mystery was one of the most iconic screensavers bundled with the Windows 95 Plus! Pack when it dropped in August 1995, right alongside classics like Flying Windows and 3D Maze. If you had a PC in the mid-90s, you probably remember it: a simple black screen with random geometric shapes and colors fading in and out, almost hypnotic, like your computer was quietly showing off. The Plus! Pack wasn’t free—you had to buy it separately—but it gave your beige box a little personality before Windows 98 introduced its own batch of enhanced screensavers. Mystery wasn’t flashy, didn’t need to be, and for a lot of us, seeing it glow on a CRT late at night just feels like pure childhood nostalgia.
