This interesting project by Jeff Halter (via Daring Fireball) lets users run the original 68k After Dark screen saver modules on modern Macs. Here are the details.

’Run classic After Dark screen savers on modern macOS’

Depending on how long ago you started using or getting interested in Macs, you likely remember After Dark, a collection of screen savers that became a fixture on Macintosh computers throughout the 1990s. At the very least, you’re possibly familiar with the famous Flying Toasters screen saver.

Over the years, running these classic screen savers has generally required vintage hardware or a classic Mac OS emulator, which can be finicky. However, a new project called Afterglow makes the process much easier on modern Macs.

As John Gruber noted on Daring Fireball, the project comes from Jeff Halter, who previously created Lunacy, a native Swift app that lets users play the classic Lunatic Fringe game from More After Dark on modern Macs.”
