A native Matrix-style screen saver for modern macOS
With older Matrix screen savers broken on recent macOS, Claude Code built one, moving from Python and TypeScript to a 500KB Swift .saver.

The full story
The poster wanted the Matrix falling-character effect as a macOS screen saver, but the best-known ones were outdated and no longer worked on recent macOS. Claude Code first built it in Python, then TypeScript, but both generated a video that Swift wrapped into a .saver file, which was over 80MB and restarted at the end of each loop.
Moving everything to native Swift brought the screen saver down to 500KB. The poster still wants to add the original typeface, make the look more blurred and washed out, and improve the character randomisation.
