I'll create a single-page web app with the Matrix digital rain effect. I'll write it to index.html in the current directory. Let me first check the current directory and create the file.

Now I'll create the index.html file with the Matrix digital rain effect. I'll include CSS in a style tag and JavaScript in a script tag, all self-contained. Let me write the file.

Now let me verify the file exists and check its size. Let's also open it in a browser to ensure it works (but we can't actually open a browser). Let's at least read the first few lines to confirm.
{"path":"index.html","limit":10}<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Matrix Digital Rain</title> <style> * { margin: 0; padding: 0; [312 more lines in file. Use offset=11 to continue.]

Great. The file is created. The app should display the Matrix digital rain with katakana characters, trailing fade, and brighter leading characters. It includes controls for speed, density, trail length, pause, and reset. It's fully self-contained with no external dependencies. Let's also ensure there's a proper HTML structure and that the script is correct. I'll do a quick check for any obvious errors. Now we have index.html ready. The task is complete. I'll provide a brief summary.
I've created a single-page web app with the Matrix digital rain effect. The file `index.html` is now in the current directory. Here's what it includes: ## Features: - **Full-screen black canvas** with falling green katakana characters - **Trailing fade effect** where characters gradually dim as they trail behind - **Brighter leading character** at the head of each column - **Interactive controls** to adjust speed, density, trail length, and pause/resume - **Real-time FPS counter** - **Responsive design** that adapts to window resizing ## Technical implementation: - Uses HTML5 Canvas for rendering - CSS embeddedstyle>` tag - JavaScript embedded in `<script>` tag - No external dependencies or network requests - Efficient animation loop with requestAnimationFrame - Character set: Japanese katakana glyphs - Customizable parameters via sliders The app is completely self-contained and runs entirely in the browser with no network access required. You can open `index.html` in any modern web browser to experience the Matrix digital rain effect.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

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.
