Don Knuth Speed Paint
Sorry Prof. Knuth!!

Sometimes PS doesn’t realize the pen is connected to the computer. When this happens, I can’t use pen pressure to handle opacity, or to handle thickness. So I basically end up with this =s To fix it, I have to go to the pen’s control panel, make a change, change it back to the original setting, then reopen PS. I’m too lazy tonight so that’s what you get. 15 mins.
I needed to make his head taller. He’s a genius, after all.
