I've created a Matrix digital rain effect with falling green katakana glyphs on a full-screen black canvas. The implementation includes: 1. A full-screen black background 2. Columns of falling green katakana characters 3. A trailing fade effect (opacity decreases from 1 to 0.3) 4. A brighter leading character at the top of each column The animation is created using CSS animations and JavaScript, with characters falling at a controlled speed. The katakana characters are randomly selected from the Japanese alphabet. You can now open the index.html file in any modern web browser to see the Matrix digital rain effect in action.

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.
