Faces in the Dark draws cartoon faces in the style of Chernoff faces. “Type” designates how the faces will look. “Normal” faces are random but will not look very weird or different. “Abnormal” faces are slightly more random, “Weird” faces are random but will be somewhat normal. “Random” just makes the faces as random as they can get.

Some things to try:
Pen sizes = 0 to get just eyes staring at you.
Pen size (v) = 0 to get a weird effect.
Pen sizes high to get a “marker” effect.
