Crossposted from my psychology blog:
This picture is an ambigram, an image which can be viewed in more than one way depending on how you perceive it.
The thing about this sort of image, in particular, is that it manages to convince you visually that you're looking at two completely contradictory views at the exact same time.
What does this tell you about perception, and the way our brain processes conflicting stimuli? Can you see it as both images simultaneously, or merely as one, then the other, alternating based on how you squint or tip your head?
