This piece explores the idea of a galaxy alive with rhythm, spiraling, unraveling, and reshaping itself in response to sound. As the track evolves, so does the entire system, morphing from a tight spiral into a stretched helix drifting through space.

Built in three.js as a dynamic visualizer that evolves over time with the track.

* The entire galaxy **rotates in sync with bass frequencies**
* A **spiral warp effect** intensifies with overall energy
* Over time, the spiral arms **stretch into a vertical helix** along the Y-axis
* **Treble spikes** trigger accretion beam effects bursting out from the core
* The **camera orbit** subtly shifts the color hue across the scene

It’s all driven by FFT analysis from the Web Audio API, and everything responds smoothly to different energy levels in the music. Still runs efficiently with thousands of particles and beams on screen.

I used a creative coding editor (Juno) I’ve been prototyping sketches in lately. It’s been super helpful for getting ideas out faster while still giving me full control with a real code editor. I hand-tuned all the motion behaviors, mapped frequencies manually, and tweaked everything in context with live audio.
