What is a good picture to describe creativity?

I have a project that I need to do, and it requires a picture that represents the character of your choice. I read The Misfits by James Howe, and I decided to use Joe Bunch as my character. Joe is very creative, outgoing and also openly gay. For example, he paints his pinky finger with a different design every week. I need an idea for a picture that would describe his personality.
