Covering an unsightly concrete cube, this creation stands out due to the use of bright colours and patterns, including many geometrical shapes. Without perspective and concrete elements, unless it is the shapes themselves, it is difficult to find the meaning of this composition. As with balls, which are absent here but with which he covered a wall of the sports hall in Outremeuse, the presence of a square or a lozenge, made up of two white triangles and two red triangles, is common in the creations of David Bruce. The meaning of this recurring pattern should be sought, according to the illustrator, in the flags of the maritime code. The layering of different elements that form this code inform the passers-by that the surrounding water is of good quality. In short, David Bruce ensures a trouble-free stroll.
