There's a psych concept called "pareidolia" (I remembered the concept, but had to Google the name), which is the human tendency to perceive patterns in random stimuli. For example, seeing shapes in clouds, or seeing faces in objects (the Virigin Mary on slices of burnt toast).
At left is the red emergency door-opening button on the commuter train. I hadn't noticed the face-like characteristics until I was sitting at the correct angle.
The "stick figure" doodling just emphasizes the point.
