The Ames Illusion

“Big” me. “Little” me. Watch these two versions of me–which are really the same size–explain why I appear petite in one place on screen and large in another. The reason, in short, is that I have been trapped in a clever visual illusion, one invented 78 years ago by American opthalmologist Adelbert Ames Jr. In the HBO movie “Temple Grandin,” the main character (Grandin) recreates the same illusion for a class assignment. Watch the scene here. The video below deconstructs the trick that Ames and Grandin play on our eyes.
