William H. Alexander – “The Scream”
Author description:Edvard Munch’s expressionist ode to existential angst, “The Scream,” comes to life. On their own, Munch’s bold, curvilinear strokes give the impression of a person trembling in the face of an unnameable dread. When optic flow information is added to the image, this impression becomes palpable. Although the image of the Screamer itself remains static, it appears to pulse and throb as if experiencing wave after wave of soul-crushing despair for the futility of existence. This effect demonstrates the influence of unrelated motion cues on the perception of object movement.
