About this tool
Streams of random katakana, numbers, and symbols fall down the screen at random speeds, each column fading to black behind a bright leading character — the classic "digital rain" look. Runs entirely on an HTML canvas with requestAnimationFrame, redrawn continuously while the tab is visible.
Works as a genuine ambient screensaver, a desk prank left running full-screen, or a screen-share gag. Press Escape, or click anywhere, to exit full screen.
Questions about Matrix rain

The falling green code from the film The Matrix: streams of characters running down a black screen.
Which characters does it use?
Japanese katakana, numbers and symbols, like the original effect.
Can I use it as a screensaver?
Yes. Go full screen and leave it running; it keeps animating while the tab is visible.
Does it slow my computer down?
Very little. It draws on a single canvas and only animates while the tab is visible.
