Put your eyesight to the test: how many faces can you spot in this mysterious tree?

 

At first glance, nothing extraordinary: a gnarled trunk, a few branches, some bark texture. Yet, the more you stare at the image, the more something eludes you—like a presence that slips away. What if this plant held a secret that only careful observation can reveal? Ready to put your senses to the test and challenge your gaze with a visual game as surprising as it is addictive?

Pareidolia: Why our brain sees faces

We are programmed to recognize faces in a flash — a social reflex that has become instinctive. Faced with a random pattern (clouds, rocks, bark), our brain “completes” the image and assembles nose, eyes and mouth where there is only chance.

This phenomenon, called pareidolia , is not a mistake but a wonderful cognitive trick: it helps us to make sense of the world, even if it means imagining faces where there are none.

Visual challenge: find the hidden faces

Here is your mission: observe the tree and count the faces it conceals.
Begin at the center, where two figures seem to be conversing, their features blending with the wood's grain.
Then move toward the base: older figures appear, their deep wrinkles and beards sketched by the striations.
Finally, near the roots, youthful faces emerge, as if whispering through the shadows.
Take your time: the more you look, the more the image transforms.

Our tips for better spotting details

• Move slightly away from the screen or squint to simplify the contrasts.
• Imagine the image in black and white: focus on the shadows and the lights.
• Look for “C” or “S” shapes, typical of facial contours.
• Follow the diagonals: they often reveal an eye, a chin, or a hidden profile.

Bonus tip:  look away for ten seconds, then look back — the brain often perceives more on the “second look”.

Behind the scenes: how the artist deceives the eye

The illusion relies on a subtle mastery of negative space.
The artist plays with hollows, knots, and fissures to sketch faces, balancing emptiness and matter to blur our perceptions.
A contrast becomes a cheekbone, a sliver of bark transforms into an pupil…
It's the same principle as the Parisian silhouettes we recognize against the light: three well-placed curves are enough to create a face.

The solution to the puzzle

So, how many did you find?
The suspense is over: the tree hides  14 faces .
Three-quarter profiles, direct gazes, a variety of expressions—surprised, dreamy, mischievous.
Fewer than 14? Revisit your observation with our tips.
More than 14? You have a keen eye (or a vivid imagination, and we love that).

Want to try it? Create your own face tree

Bring a notebook, a pencil, and a photo of a textured tree.

1. Circle the areas of shadow and light.
2. Locate two “eyes” (nearby knots or cracks) and sketch a face outline.
3. Suggest more than you draw: an arc for an eyebrow, a comma for a mouth.
4. Erase the excess and enhance three key contrasts.

In just a few minutes, you will have a gallery of forest portraits, both relaxing to create and fascinating to contemplate.

Looking at things differently is already to broaden our understanding of the world.
