Gonna post my idea here, since I can't work on it until tomorrow morning, but I want feedback before I waste time...
It's gonna be a series of notes on musical notation (the five lines), all quarter notes and looking bored. At the end on the right, a really high whole note holding up fists and screaming.
I think it's a winner if I can get it done... Just trying to see what color it'd look best on... thinking black and gray-accented notes on either orange or cream.
