The BBC covered the topic of finding faces in the most unexpected places: "It's not often that you look at your meal to find it staring back at you. But when Diane Duyser picked up her cheese toastie, she was in for a shock. “I went to take a bite out of it, and then I saw this lady looking back at me,” she told the Chicago Tribune. “It scared me at first.” As word got around, it soon began to spark more attention, and eventually a casino paid Duyser $28,000 to exhibit the toasted sandwich. For many, the woman’s soft, full features and serene expression recalls famous depictions of the Virgin Mary." The 2014 BBC article is here. I don't know if the sandwich is still preserved.
I find human depictions in various places. Today's are relics of the water - crackled buoys and prove the BBC statement that we are primed to see faces in every corner of the visual world.
