Jorge Macchi installs an oversized wind rose with an axis length of around six metres above the atrium of the training centre. Its axes are not fixed, as is usually the case, but can be moved depending on the current wind speed (this is measured by a sensor on the roof of the building and transmitted to a computer that regulates the speed of rotation). The axes rotate slightly delayed and up to five times per minute in the same direction. This means that they always offer a new view of the letters N, E, W, S (for North, East, West, South).
