Vibeke Bertelsen, the creator of this project tells us more about the animation on her blog:
The animation is a part of a series of different virtual sculptures I made of human bodies and faces. Often in games and 3D art the human body is idealized into sexy or heroic archetypes but in this project the two heads are distorted and glitched in ways that create more unfamiliar expressions that sometimes dissolve into pure absctract shapes.
The animation is created in WebGL using the popular library Three.js and in order to precisely control the progression of the visuals multiple tracks of keyframes are loaded into the application in order to control animation parameters in sync with the music.
