The animated type videos were interesting without sound, however, with sound it is a lot more interesting and fits with the animation a lot better. The sound seems to guide the type. The examples were very similar in design and style, which made it a little boring to watch sometimes. I really liked the one where the letters moved according to the sounds the letters made. I thought it was really cool and really demonstrated an element of speech that you can see rather than hear.
These videos kind of remind me of a truck commercial that I saw the other day where the letters were going upside down and side ways and all different directions. It was really cool and I wish some of the videos would have been more interesting like that commercial.
