Just found out a game called The Polynomial.
“The Polynomial is a 3D musical ‘space shooter’ game, with non-shooter mode and built in fractal editor. Visuals are generated mathematically and animate to your music or microphone input; there are 4 music-driven animators and 38 arenas to choose from (12 arenas in free demo). You can create your own arenas using built in editor, and you can save your fractal images at any resolution. There are many parameters you can change for entirely new, original look; the number of combinations is astronomical. “
Here’s a fancy screenshot:

You can download the demo for free, full version is minimun $8.
