What's Wrong?

What's Wrong? is a screamer animation created by Jeremy Winterrowd, the creator of The Maze,

The animation disguises as a normal kitchen room, which consist of 2 open windows, table, chairs and paintings - the player is asked to find something wrong, However, after 30 seconds, a picture of an eyeless woman with wide mouth appears with a man screaming - the animation will repeat.

Impact
Because how this animation is so effective that it was later popularized in 2002 to 2010, there are multiple clones of this screamer that came up with the same concept, such as Forest-wmv or Basement Ghost.

The oldest copy was from TeKZoned.
