Very good
I'm not sure why some reviewers are criticizing the style of this work. I liked it - how it was strictly monotone, how the scenes and rooms faded into darkness. It seemed to fit. As far as the animation itself, the only time I really disliked it was in the very first scene (the fan blades rotating, which was done rather poorly). Other than that, the frame-by-frame was pretty good. Quite enjoyable.
