How Do I Make a Matrix Rain Music Visualizer in My Browser?

Open Data Tunnel, start the demo track, and choose MATRIX under PRESETS. Bright characters run down the tunnel walls with dimmer ones trailing behind. Watch the rings closest to you when the bass hits. They push outward first, and the movement travels into the distance.

How do I make the code readable?

1. Open FIELD and confirm that MATRIX is selected. Lower RAIN SPEED if the leading characters pass too quickly to see.
2. Shorten TRAIL LENGTH if neighboring streams blend together. Leave enough trail to see which way the code is moving.
3. Open CHARACTERS. Try BINARY for zeros and ones or KATAKANA for Japanese katakana. Use CUSTOM and enter a short set of letters in CUSTOM CHARACTERS to give the rain a different alphabet. The effect draws from those characters throughout the tunnel.
4. If individual characters still blur together, lower GLOW in LIGHT. Keep the foreground large enough to read with CHARACTER SIZE.

How do I get the beat to travel down the tunnel?

Open WAVE while the track plays. Raise WAVE AMOUNT until you can see the rings widen on a bass hit. Then raise ECHO DELAY to give the near and far rings more separation in time. BEAT RINGS controls the brightness of the ring that marks a hit. Back it off if those rings make the falling code hard to follow.

RAIN SPEED sets the pace of the streams on the walls. FLY SPEED, under FLIGHT, controls how fast the camera moves through the tunnel. Slow the flight first if the whole picture is moving too quickly. You can still keep the rain moving.

What else can I do with the same tunnel?

Try AMBER ARCHIVE for warm typewriter letters. CYAN CORKSCREW puts bright binary digits on a twisting wall. Both use the same tunnel with FIELD → NONE. If you want falling code in a different color, start from MATRIX and change the PALETTE in COLOR. The preset gives you a working rain setup before you change the ink.

Data Tunnel generates its own 3D scene. If you want characters to follow the shapes in a portrait or clip, use the separate video-to-ASCII workflow. The Data Tunnel guide lists the character sets and modulation controls.
