After linking to Stacks, his remarkable new modern HyperCard player, I made the terrible mistake of clicking around the rest of Jeff Halter’s website, and fell upon Lunacy:
Created by Ben Haller and released in the early ’90s as part of the Macintosh More After Dark software package, Lunatic Fringe was unique among screensavers in that it was not just a passive animation to watch, but an interactive game! Toggling the Caps Lock key while the screensaver was running popped you into a space shooter where you could fly around, collect power-ups, and blast a variety of baddies all in pursuit of a high score. It was a blast.
Running Lunatic Fringe on a modern computer has been a challenge. Fringe Player by Greg Parker filled this need during Apple’s PPC and Intel era, but is not supported on modern Apple platforms. Lunacy brings Lunatic Fringe to the present: a native Swift app with a built-in emulation engine that runs the original module, unchanged, on modern Apple platforms.
Lunatic Fringe is one of my all-time favorite classic Mac games. Lunacy is a great modern player, including CRT simulation to make the game look a lot more like it did back in the day.
