This weekend I downloaded Pink Floyd’s “Dark Side of the Moon” CD. While searching the internet, I found several pages dedicated to the synchronization of The Dark Side of the Moon with The Wizard of Oz. Supposedly, if you start the CD playing just as the movie starts, it will sync up perfectly and secrets to the universe will be explained, or some such dribble.
In the end, I found the whole thing a waste of time, and we ended up having a lot more fun just watching The Wizard of Oz regularly.
