Can YOU tell which table is bigger in an optical illusion?

To the average person, the two tables appear to be different sizes – one seems to be long and narrow and the other resembles a square. However, what has sent shocks around the internet is that both tables are identical. Called the Shepard's tabletop illusion, this phenomenon plays tricks on the way we perceive depth and by manipulating the tabletops, viewers will then see that they are the same shape.
