WHAT IS IT?
This model presents five classic optical illusions.
HOW IT WORKS
The optical illusions are constructed using a combination of NetLogo turtles and patches.
ILLUSION #1 -- White circles on a gray background produce an illusion of the circles changing colors between black and white, depending on where you focus your eyes.
ILLUSION #2 -- Diagonals moving away from the center create an illusion of depth, which makes the parallel horizontal lines seem to bend in the center.
ILLUSION #3 -- The perpendicular lines that do not match row to row create an illusion of the lines between them being not parallel.
ILLUSION #4 -- Relative sizes of other circles skew the perception of the middle circles, creating an illusion of difference in size.
ILLUSION #5 -- Circles of diamonds seem to rotate you focus your eyes on their center.
