Pattern moves

Each pattern moves in its own way with the bass, mid and treble of the music. Meter already draws the music, so it stays as it is.

Video

Show your camera or a video file on the lights. Nothing leaves this device.

Colors

Marquee text

Scrolls when a layer is set to Text.

Android app

An Android app that shows the panel full screen, keeps the display awake, and lets Sound listen while your Bluetooth music keeps playing.

Built 25.09.2026. Chrome often calls an app file risky: open its downloads and choose "Download anyway", then tap the file and allow installs from your browser. Everything you see here updates on its own inside the app, so a new download is only needed when the app around it changes.
