Digital rain is a quotation, not a genre. It comes from the title sequence of the 1999 film
The Matrix, where the code of the simulated world was drawn as columns of glyphs streaming
down a black screen in phosphor green. The glyph set is its own invention: half-width katakana
run through a mirror, mixed with a few Latin numerals, so the wall looks like writing and reads
as nothing. Nearly thirty years of loading screens, hacker montages and conference backdrops
later, the picture has become a stock signal that means a computer is working on something the
viewer is not meant to follow.

Everything about the effect is in the columns rather than in the palette. Each column falls at
its own speed and respawns above the top edge when it clears the bottom, so the field never
pulses in unison. The leading glyph is drawn near white and the ones behind it fade back through
green over eight or ten cells, which is what makes a stream read as falling rather than as a
list scrolling. And a cell keeps whatever glyph was written into it as the head passed, with new
characters appearing only at the front, so the wall churns without the whole grid flickering.
Get any one of those three wrong and it stops looking like the reference.

Two duties come with using it. It is decorative motion with no informational content, so it
answers [prefers reduced motion](/prefers-reduced-motion) with a still frame rather than a
slower one, and it should pause when it is off screen. And it is a moving wall of mid green on
black, which means no text laid directly on it has a stable [contrast ratio](/contrast-ratio):
the ground under any given letter changes several times a second. Type over digital rain needs
an opaque plate of its own, exactly as type over video does, and a specimen that puts a headline
straight onto the field is showing a legibility problem rather than a background.

The word is worth keeping separate from its neighbours. A [particle background](/particle-background)
is the generic case, any field of small moving agents behind the content, and it can be any
colour going in any direction; digital rain is one specific screen with a fixed palette, a fixed
glyph set and one direction, which is why quoting it is a reference and inventing it is not
possible. It sits inside [terminal aesthetic](/terminal-aesthetic), whose monospace grid and
green-on-black phosphor it borrows wholesale, and beside
[fictional user interface](/fictional-user-interface), which is the wider practice of screen
graphics drawn for a camera rather than for a user.
