An optical illusion (not from stareclips.com) is a screamer video. The video tells the player to look at a black dot in a negative image of a landscape. The landscape then turns black and white. At 0:32, a continuously looped bad contrast video of a boy yelling at the camera is shown along with the creator's scream.
