Created a complete Matrix digital rain effect in a single self-contained HTML file. The implementation features: - **Full-screen black canvas** that automatically resizes with the window - **Columns of falling katakana glyphs** (plus some alphanumeric characters for variety) - **Trailing fade effect** using semi-transparent black overlay (`rgba(0,0,0,0.05)`) that creates smooth motion trails - **Bright leading character** in white with green glow, followed by bright green characters, then progressively fading to faint green tail characters - **Individual column speeds and lengths** randomized per column for organic variation - **Continuous regeneration** of streams that reset when they scroll off-screen - **Subtle glow effects** using canvas shadow blur on the leading characters Open `index.html` in any modern browser to see the digital rain in full-screen effect.

EVALUATION

4/5 working

Classic Matrix digital rain with green katakana columns, fading trails, and bright leading chars; animates continuously, no interactivity but not required.

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.
