The Hollow Face Illusion is spooky. The photo is of a flat sheet of plastic with a facial mask pushed in one side. In this case it’s the face of Albert Einstein*.
People with "photographic memory" are thought to be able to take and recall mental snapshots without error. But there is no evidence this type of memory exists.

Neurons in the eye turn light into electrical signals. How and where signals travel between these cells is thought to affect vision.
Synesthesia is a condition in which stimulation of one sense automatically evokes a perception in an unstimulated sense.
