Optical Illusions

Optical Illusions
Optical Illusions is a game made by Jeremy Winterrowd in 2006. The game shows the player some pictures and asks them questions, like "How many faces do you see?" After about five illusions, Sarah, from the film Exorcist: The Beginning, appears, punches the screen and screams, before cutting to a still image of her. The same animation is used in other games made by Winterrowd, like Find It, Hit the Dot and Bubble Wrap Maniac. (In the last two, the animation ends with the image of Regan MacNeil instead.)
