Amazing Mind Trick Illusion
The video shows some instructions and then invites you to follow a 3D red dot jumping around with a picture of a forest in the background with your eyes. However, after 36 seconds, a red computer-animated 3D head jumps in from above, moves rapidly and screams at the viewer. Then the text "Gotcha!" is shown, with a link to the channel of the author. There is a copy of the video called "folge dem roten punkt.mp4".
NOTE: The following video contains a screamer!
