Weak developer Felix Rieseberg has turned Mac OS 8 into an application that you can install on your Mac or PC. After transforming Windows 95 into an application in 2018, Rieseberg decided to turn the entire 1991 Macintosh Quadra with Mac OS 8.1 into one Electron application. It even includes a number of applications and games, thanks to an old MacWorld demo CD from 1997. The application can be installed on macOS, Windows and Linux.
If you are interested in trying out the app, all standalone versions are less than 250MB and can be downloaded from GitHub. Enjoy, again, a journey down the memory.
