It would be a fantastic hack if they were using some cool algorithms/machine learning to separate the sounds, analyzing their timing, then dynamically generating the animation from that. I would be genuinely interested in discussing that. But not this, unfortunately. Seems to be a simple (albeit well-done) cg video set to some music.
