There are cool Web apps that use YouTube’s API to provide a much better viewing experience than the standard YouTube site. We shared with you previously:

• MyStrands: Automatic playlist/ music video player
• iDesktop: resizable Youtube player window
• Songza: Music Serach Engine
• Oskope: Search YouTube

Today, you can add to the above list:  YouTube Fast Search, a cool web application that allows viewer to play videos and search for new videos non-disruptively.

Users can build a playlist  from search results and add new videos to the playlist without interrupting the playback. The interface is similar to the one from MSN Video, users can edit the playlist and enlarge the video to there liking.
