I just found out about these music videos from my Alan Parsons' e-mail list. Both videos are highly imaginative in their mixing of music and computer graphics. The songs played in the two videos are different from each other (although the "layout" of the instruments is the same), so be sure to watch both. The run time for Pipe Dreams I (above) is 3:27; Pipe Dreams II (bottom) is 3:55. Enjoy!
There are a number of other Animusic videos available at Youtube. Check them out here.
