What is Neural Drift: A Julia Set That Follows the Melody?
Neural Drift is the name Vortexia’s dashboard gives its Julia set engine, one of the three on the free plan. The name is a label, not artificial intelligence: the shape comes from the Julia set, a fractal defined by a single number that Vortexia keeps moving. That number drifts slowly on its own, so the picture morphs even in silence, and the mids in your music push it further, so the whole structure changes shape with the melody rather than simply swelling with volume. The bass makes it breathe, each kick lands a short punch, and the treble makes the colours more vivid, while the colours sweep round the wheel about every 20 seconds. That constant, smooth change suits melodic, vocal and lo-fi music.

Frequently asked questions
Is Neural Drift AI?
No. The name is just a label. It is the Julia set, a classic fractal, calculated live on your graphics card.
Why does the shape keep changing?
A Julia set is defined by one number. Vortexia moves that number slowly on its own and pushes it with the mids in your music, so the whole shape morphs with the melody.
Is it free?
Yes. Neural Drift is one of the three engines on the free plan, with Chaos Prime and Solar Flare. The free plan streams at 720p and 30fps with a small watermark.
Which music suits it?
Melodic, vocal and lo-fi music, where the mids carry the tune. Kick-driven tracks still land a punch on every beat.
Does it need music to move?
No. It keeps morphing on its own; music adds to the movement.
