Scientists studied whether human's could identify with abstract shapes, to assign a triangle thoughts, feelings. They of course could. This triangle was angry. This one was scared. Devoid of stimuli the brain seeks recognition, applies logic to nothing to make sure the world retains solvency, coherence as defense against the face of meaningless abyss. This is how god exists. This is how Peter Halley's paintings exist. It's called Prisoner's Cinema.
