Using text and voice to seek funding.

An interesting ad.  I saw something similar done with a book trailer and it seem to be the relationship between the qualities if the voice and the text and the text that make it work.  I was wondering why the text us rotated and the only thing I can come up with is to keep it interesting.  The behavior of around seemed to emphasize that word and I am not sure why that choice was made.  Except for the climax was reached when both the text and her voice stopped and then it went on to feature the children's hospital that was the purpose of the ad.
