This sci-fi [0] music player with automatically generated visualizations. https://glitchy.website/
Eventually I will make it more like an actual music player since right now it only plays one file and provides different seek points so you can jump to the song you want to hear. I think it will also be an interesting way to keep me invested in releasing new music that I can put on it.
