That tiny figure is a tightrope walker, crossing a wire on the Atomium monument in Brussels, Belgium.
The wire's suspended about 70m above the ground and is about 70m long too.
Don't look down! It's not the first time the famous monument has had tightrope walkers on it.
The Atomium monument is 102m tall. Its nine spheres are in the shape of a unit cell of an iron crystal, magnified about 165 billion times. It was designed for the Expo in 1958.
The wire will stay in place until 18 August - but we'll leave the daredevil antics to the experts, thanks.
