Hmm, last time we saw something like this, the illusion was horizontal. Does it work in vertical mode as well? You decide! Apparently the building pictured in this article stands perfectly upright, and has the same width of it’s footer, as of it’s last floor. How can it be? Why do we see it shaped as an upside-down trapezoid? Could it be only because of the black and white tiles used in the building’s facade? My guess is that we are dealing with a classic example of a Cafe Wall illusion, which messes with our brain, making us believe the edges are bent.
