Gezichtsbedrog

Gezichtsbedrog is a screamer video uploaded to YouTube by a user VideosOfHeaven on December 21, 2008.

The video consists of several different optical illusions. The first illusion is a picture of a man's face that changes when the viewer squints their eyes. The illusions continue for about 4 minutes until the last illusion of a blue dot inside a larger green circle is displayed. The viewer is told to stare at the dot in the middle, but after 10 seconds, a picture of Amy Peterson appears accompanied by a loud roar.
