An Optical Illusion (Not from Stareclips.com)

An optical illusion (not from stareclips.com) is a screamer video made by a YouTube user hotogainc on April 21, 2007.

The player is invited to look at the black point in a negative picture of a landscape in the game. The scenery abruptly changes from black and white to black and white. After 32 seconds, a low-contrast, continuous loop video is shown in which a boy screams into the camera while the creator's scream begins to play, which can already be said that the concept of this screamer is badly-made or intended to be a joke in particular.
