Watch what happens with the size of these cigarettes. The background drawing is what really tricks us here. The white wall with the grid lines plays a big part in causing us to subconsciously think that we are seeing a 3 dimensional scene instead of 2 dimensional. Our eyes and brains have naturally been trained to pick up visual cues and define dimensional planes of what we are viewing. The 2 "horizontal" lines in the middle of that white wall start to converge as they "go" from the left cigarette to the right cigarette. This tricks our visual systems and creates the optical illusion that the cigarette on the right is much bigger. So, the optical illusion is created by the way our visual systems interpret the surrounding drawing and not by the cigarettes themselves. Our sense of dimensions, depth, and actual sizes are easily fooled!
