Dr. Harms' Ink Vomit
A cure for all your ills!
After nearly a 10-year hiatus, I started practicing drawing again after getting my PhD in fall 2022. I work mainly with fountain and dip pens. This is scientifically the best medium because (1) it is binary: ink or not? (2) you cannot cheat (i.e. erase), and (3) fountain pens are the greatest invention of any humanoid species.
