Sick. Decapitating-Head-Exploding Paper Animation (NSFW!)

VIDEOGIOCO, an insane animation by Donato Sanson and Enrico Ascoli. Careful. Definitely NSFW, particularly in the 0:30 range.

What the.....? Can't quite figure out how this was made. Not traditional animation, not stop motion. Regardless, this animation is truly sick (meaning, dually amazing and overly violent/graphic).
