This project is a web implementation of the raining green code seen in the Matrix franchise. It’s built right on top of the upcoming graphics API WebGPU, but falls back to the functional WebGL wrapper, REGL; its previous Three.js version is maintained in a separate branch.

I used to spend countless hours in college scouring the web for the best digital rain screen saver for my laptop. Sounds like the author is with me on that:

The number of implementations out there of this effect is a testament to the size of the film’s impact on popular culture. For decades, I’ve enjoyed searching for and comparing them from time to time. That’s probably how you arrived here— it’s fun to see what kinds of solutions different people come up with to a problem, when the process is purely recreational and its success is subjective.

This one’s really nice and even has a 3D mode. The README says it’s “made with love”, but from what I can tell it’s almost entirely JavaScript. 😜
