- Choose one of five presets in the left sidebar.
- Adjust its six sliders to change motion, scale, two colours, intensity, and grain. Each preset keeps its own settings. Reset restores the selected preset.
- The preview advances to the next preset every four seconds when idle. Editing pauses the cycle for eight seconds; Pause/Resume controls it manually.
- Export current preset copies a standalone HTML file containing the animated WebGL2 canvas, GLSL shader, and current settings. Paste it into a new .html file to use it.
