These short zombie animation clips are superb. I watch them over and over. There are at least 3 different videos in the series. Other than the 2 listed by the first reviewers, the third animation involves a zombie clawing it's way out of the ground. Like the other clips, there is humor but I won't give anything away.
I don't know if this 3rd animation is anywhere online. I downloaded these years ago from the animator's website, before youtube. The resolution is pretty good.
All three are done almost as teaser trailers for a movie that was planned, but never got made. I often wonder what happened to the guys that made them.
