Doodling
I just realized the reason doodling is so important is because it is so telling of us. We doodle only when we are so very distracted by something else, that a part of our bodies (and with it a part of our minds) has felt free enough to produce without effort. That’s kinda wow. You might call it Art of the Subconscious, but since there’s already so much “Subconscious Art” (and people would surely miss the enormous novelty of this new term), we better call it something else. Upon reflection, “doodling” is perfect.
