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.
thinking
The user wants me to create a Matrix-style digital rain effect as a single-page web app. Let me build this with: 1. Full-screen black canvas 2. Green katakana characters falling down 3. Trailing fade effect4. Brighter leading character at the front of each column I'll use a canvas element with JavaScript to animate the rain effect. Let me create this as a self-contained index.html file.

The file has been written. Let me verify it looks correct by reading it back.
The file is ready at `/workspace/index.html`. Here's what it does: | Feature | Detail | |---|---| | **Canvas** | Full-screen, resizes with the window | | **Glyphs** | Random katakana chars (U+30A0–U+30FF) | | **Leading char** | White with a green glow (`shadowBlur`) — stands out as the brightest point | | **Trailing fade** | Each column keeps a history of 12–30 recent glyphs; green intensity and alpha fall off linearly with distance | | **Variable speeds** | Each column drops at a random speed (0.35–1.0 rows/frame) for a natural look | | **Reset** | Columns respawn at the top with a randomised delay when they fall off-screen | | **Persistent trail on canvas** | A translucent black overlay (`rgba(0,0,0,0.08)`) is drawn each frame, so older glyphs naturally fade out on the canvas itself | Open `index.html` in any browser — no dependencies, no network calls.
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.

EVALUATION
Classic Matrix digital rain with green katakana columns, fade trails, and bright leading chars; animates continuously but doesn't react to input.
Vision grade · anthropic/claude-sonnet-5
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.
