Steady fixation is a term used in optics when the eyes are fixed on a point with no blinking or movements. In motion induced blindness, steady fixation causes disappearance of the yellow dots in the video below. When you blink or shift your gaze even the slightest bit, the dots will reappear.

4

Created by Michael Bach, this cube presents itself first as an object with a missing corner. There are two more interpretations: "daughter cube" and "room corner". To realize the daughter cube, stare at it long enough to see that the gray zones are actually one cube attached to the larger cube.

Optical Illusions In Transparent Monitors

4

You may have seen these before, monitors that have the view directly behind it set as a wallpaper. These give the illusion that the monitor is transparent by displaying a non-real-time view.

How To Change The Perception Of Color

4

Derren Brown convinces a subject that yellow is red, and that red is black. Officially this is termed as Conversational Hypnosis, but can also be referred to as Magic Hypnosis. I wonder if the same technique can be used with a deck of cards?
