The beauty of great data visualization is that it renders wildly complex information into easily digestible pieces. What was once complicated still is, but now it's much easier to understand. Music does that in its own way, taking individual notes that fit together via incredibly complex patterns and stringing them together to make a rich and nuanced flow that gets past the complexity. When the two come together, you get something like this. Prepare to be mesmerized and blow part of an otherwise productive day with Igor Stravinksy's The Rite of Spring, visualized, from the people at The Music Animation Machine.
