Optical Illusions > Traditional Line Illusions
A very tradional illusion. You see three posts but cannot see wher the middle post begins.
Is the tower you see right side up or upside down?
Do your see the faces amongst the vases? How many do you see?
This is one illusion that is almost impossible to see the straight lines even when you know the illusion.
Both lines are the same size, even though one seems longer.
