If you find all the hidden faces in this optical illusion in less than 10 seconds, you are among the people with the best eyesight.

Why does this illusion still fascinate us today?

Unlike modern illusions often supported by advanced technology, “The Tree of Appearances” is based on a simple but incredibly effective principle: our brain loves to spot patterns. Faced with this image, our minds naturally activate to identify familiar shapes. But these hidden faces require a special effort: breaking out of our usual perception patterns.
