"It doesn't really exist; it's just basically lots of different stages between the two pieces, and you end up with, like, a third shape that doesn't exist but is suggested to you by the image"

This quote by Sean Booth is describing the principle of optical illusions. Visual fallacy are images that seem something, but when taken a look at from a different point of view, can be viewed as something else. Cubicle is saying that visual fallacies don't in fact exist, however rather they are a combination of two different shapes that when combined, produce a third shape that isn't actually there. This 3rd shape is only recommended to the viewer by the image. This quote is an excellent example of how optical illusions can be used to fool the eye and produce something that isn't actually there. Optical illusions are a great way to challenge the way we perceive the world around us and can be used to produce fascinating and distinct art.
