This optical illusion picture was taken from the Little Giant Book of Optical Illusions by Keith Kay, where it was originally presented as a puzzling pattern containing hidden black and white cows. As easy it was for me to spot the one hidden cow in it (what’s with all them cow illusions?!), I was never able to see any other cows present. What do you make of it? BTW, this kind of Rorschach Test optical illusions proved quite popular in our archives, so make sure you check our spot the object category for more -they should be buried somewhere in there…
