A fractal tree grown with an L-system algorithm rotates gracefully while thousands of cyan-to-violet particles shimmer along its branches, creating a seamless 4 K 60 fps loop. The glowing structure evokes neural networks, digital nature and ethereal magic at once, making it an eye-catching backdrop for fantasy trailers, mindfulness apps, science-art exhibitions, eco-tech keynotes, VJ LED walls and seasonal holiday idents. Its calm motion leaves space for titles or logos yet instantly fills the screen with a sense of wonder and organic technology.
