It’s either an animated short or a music video. It depicts a man’s face which begins to rotate, revealing an identical face on the back of his head. At one point the eyes follow the viewer as the faces continue to rotate. Eventually the rotating stops and several wounds appear on the face and black blood seeps out. Then the face melts before under going several more transformations. I believe at one point it morphs into a house fly which breaks apart into two clean pieces. I probably saw this video 3 years ago.
