In this optical illusion that's gone viral, the trees seem to be watching you. Faces are hidden in the branches, appearing and disappearing depending on how you look at the image. Some see three, others ten… and everyone is convinced they're right. And you, how far will your gaze wander?
When a single image shakes our certainties

The first time I saw this illustration, I thought it was just a simple landscape: a few trees, a light background, nothing special. And then, after a few seconds, a detail changed everything. A curved branch formed a forehead, a shadow took the shape of an eye, then a second… and suddenly, it was impossible to ignore these hidden faces. As if the forest itself had started looking at me.
