Müler - Lyer Illusion

Have a look at the red lines on the drawing. They are exactly the same size ! There are a few explanations for this phenomenon, one of them being that the lines on the top and bottom suggest a perspective (which is actually drawn here). The illusion works fine without the ticket scene, too.
