That's how deep this rabbit hole goes, friends. (Please support the [Internet Archive!](https://archive.org/about/)) - **Make it look sweet in 2D**. This is not a cop-out. There is just no scene in the movies as iconic as the digital rain itself, and while depth effects are cool, they take away from these other details that make the difference between a goodtrix and a *greatrix*. - **The glyphs are in a *fixed grid* and *don't move*.** The "raindrops" we see in the 2D effect are changes in the brightness of symbols that occupy a column. To get a closer look at this, try setting the `fallSpeed` to a number close to 0. - **Get the glow and color right.** Matrix symbols aren't just some shade of phosphorous green; they're first given a bloom effect, and then get tone-mapped to the green color palette. - **Symbols change shape faster as they dim.** When symbols light up, they almost never change shape, but their cycle speed increases the darker and darker they get. -- **Two "raindrops" can occupy the same column.** This is complicated, because we can't allow them to collide. +- **Two "raindrops" can occupy the same column.** This is complicated, because we can't allow them to collide. A useful approach to thinking about this is, each column's glyph brightness is a kind of [sawtooth wave](http://mathworld.wolfram.com/SawtoothWave.html). - **Capture the glyph sequence.** Yes, the symbols in the sequels' opening titles, which are arguably the highest quality versions of the 2D effect, change according to a repeating sequence (see `glyph order.txt`). - **Make it free, open source and web based.** Because someone could probably improve on what I've done, and I'd like to see that, and maybe incorporate their improvements back into this project. +- **Support as many browsers and devices as possible.** This project used to rely on Three.js's GPUComputationRenderer, which only worked in browsers supporting WebGL's [oes_texture_float extension](https://caniuse.com/#search=OES_texture_float). The rewrite dropped this dependency, and gained support for a broader range of browsers and devices. - **Whip up some artistic license and depict the *previous* Matrix versions.** The sequels describe [a paradisiacal predecessor](https://rezmason.github.io/matrix?version=paradise) to the Matrix that was too idyllic, [and another earlier, nightmarish Hobbesian version](https://rezmason.github.io/matrix?version=nightmare) that proved too campy.

And here's the thing: **The Matrix is a story about transitioning, directed by two siblings who transitioned**. So there! There's plenty more themes in it and its sequels than that, and plenty of room for interpretation, but no room for the misogynistic ideas that led to that gross subreddit we all know about.
