Headscribbles is a collaborative web comic written by Jennifer M. Hartsock and illustrated by Jordan Harrington. After Molly abandons what she believes is nitrous oxide intoxication, she explores everyday adventures while her brain passenger conductor her on how exploration should be done.
The Brainipedia page says: “The brain is the most complex object in the known universe, in which “you”-stuff comes from. It’s also the epicenter of where random thoughts pop up while you are trying to sleep or do anything productive. Those horrible things that happened years ago that nobody remembers? Yup. That’s your brain, just being a jackass.”
