What you see here are two identical cigarette lighters, but they exist in two separate dimensions.
Allow me to explain: one of these lighters is real and therefore exists in the 3rd dimension, sans glasses. As for the other one, it was a printed on some printer and is therefore two-dimensional.
Remember those chalk-art designs that looked like they were coming out of the street? It is similar to them, and it creates a very interesting optical illusion.
This, and other photos that you can view at my Source link were designed by Julian Beever.
