This is cute: graphic design inspired by music. My only complaint is the user experience: I don't want to have to click to the next page/song and press Play, although I understand that the former feature could have been purposefully implemented to prevent a listener from missing all of the visuals if he Tabs away listening to the tunes and forgets to for the visuals.

I always enjoy Nicholas Felton's Annual Report and this year is no exception, although I find the triangle pattern obtuse at times and I wonder if there is a way to use such meticulously collected and organized data to tell a more rich and human story?
