This post is a departure from what I usually write about because I just spent a few minutes gazing at this mindblowing optical illusion and I was totally freaked out, so I need to ask…

Does this work for everybody? The brain is a wondrous thing…

Schroeder stairs is an optical illusion, a two-dimensional drawing which may be perceived either as a drawing of a staircase leading from left to right downwards or the same staircase only turned upside down, a classical example of perspective reversal in psychology of perception. It’s named after the German natural scientist, Heinrich G. F. Schröder, who published it in 1858.
