This is some thing stylistically that in experimental animation that is hardly new, the dynamic triggering of sound via animation is some thing that has been done since the mid-late 1980's but done with hand drawn animation. The is a dynamic discord between the music (sic) and animation designed to provoke a feeling of been fractured or shattered in the mind, the vary being of the viewer at both the physical and psychological level.
The random (Semi) nature of the sound/ music scape (sic) and the color pallet of the animation provide the auditory and visual counterpoint in the mind of the viewer that for a time takes you on a journey of sorts for the brief time you are watching.
