junk- I hope this didn't take the author much time
I've seen this idea work before, but this was a miserable failure. Firstly, the sketches should react to the changes in the music. For example, when the music makes quick, sharp notes, a jagged line could be appropriate. Secondly, the music must have variation, ("ups" and "downs")- not a mind-numbing funk beat. This was not original. The author simply borrowed an old idea, and then proceeded to thoroughly f' it up.
