Create the Matrix digital rain effect on a full-screen black canvas: columns of falling green katakana glyphs with a trailing fade and a brighter leading character.

The user wants me to create the famous Matrix digital rain effect in a single HTML file. This is a classic canvas animation that features:

1. A full-screen black canvas
2. Columns of falling green katakana characters
3. A trailing fade effect (characters get darker as they fall)
4. A brighter leading character at the front of each column

Let me create this in a single self-contained HTML file with inline CSS and JavaScript.
write /tmp/ws/index.html (3646 bytes)

The file was created successfully. It's about 3.8KB which seems right for the content. Let me confirm the file is complete by checking the last few lines.

Created `index.html` with the Matrix digital rain effect. The file includes: - **Full-screen black canvas** that resizes with the window - **Katakana glyphs** mixed with Latin letters and symbols for authentic matrix feel - **Trailing fade effect** using `rgba(0, 0, 0, 0.05)` overlay on each frame - **Brighter leading character** - the first ~10 characters in each column appear in bright white, transitioning through fading green as they fall - **Randomized drop timing** for natural staggered appearance The animation runs at ~30fps using `setInterval(draw, 33)`. Simply open the file in a browser to see the effect.

TAKE IT TO CODE

EVALUATION

4/5 working

Classic Matrix digital rain with fading green katakana columns, animates continuously; inputs don't add interactivity but effect looks good.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
