On the first day I came to Taiwan in 1998 I was alone and very confused. In the evening I found myself in the basement of the Shin Kong Mitsukoshi building and decided to go to the viewing deck. Since then I have always enjoyed seeing Taipei from the sky and have gone to the top of 101 many many times.
The movie below shows the building of 101. They show the movie in a small viewing room on the viewing deck. The movie is great and the 2007 fireworks awesome. I remember at the time there was much controversy since they allowed Sony to advertize their brand prominently on the side of the building but there was no mention of Taipei. Just business!
Anyway, enjoy the show and feel free to comment.
