Typography in motion

This is a very nice job about typography. The black and white are used as the two main colors in this clip. The white letter is floating and floating in the black background is smooth and it is like the star on the sky. As the clip used the effect zoom in and out letters, that is so great.
The second part of the clip you can see some other color such as blue, yellow, red and pink. This part also has the present of human. It looks like she walks in the wood of letter. She is not clear and some how blur.
This is really a good clip. I wonder that what software they used to make this clip. At first, I think it might make by flash but after that I changed my mind. It may be made by Adobe After Effect.
