I built an open source real-time music visualizer that lets you create animated color themes simply by describing them with natural language prompts. ChatGPT helps convert your descriptions into live visual styles.
The visualization is fully customizable and powered by DSP and GPU shaders.

Also, I noticed there are shaders in that config. Have you tried doing special effects with that like bloom or CRT effects?
