I've made a Video Collection of 10 Tallest Skyscrapers in the World

You've probably seen photos of those supertall skyscrapers, but did you see them all on video? I really don't like picture slideshows, and that was all I could find, so I've decided to make a real video by myself, and fill the gap in YouTube content.
This is the collection of professional and amateur videos, collected from YouTube, and made in iMovie 08 with over 50 clips.
