At first glance, it looks like a completely ordinary photograph: a brick wall, with nothing particularly striking about it. But there is an object hidden among the bricks, and finding it can become a surprisingly difficult task.

The image is one of those visual illusions that play with the way our brain interprets patterns. The object is in plain sight, but the colors, shadows, and lines of the bricks make it go unnoticed during the first few seconds.

The clue we’re giving you to solve it is as unexpected as the image itself: Fidel Castro. It has nothing to do with the Cuban leader appearing hidden in the wall, but rather with the object you have to find.

Once you finally discover it, something curious happens: you can no longer stop seeing it. The next time you look at the photograph, you’ll probably find it within a matter of seconds.

Now comes the challenge: how long did it take you to find it?
