**Concept**

The idea was to create a geometrical pattern which can change and be perceived as a different volume from different angles. Leonardo da Vinci drawings were our inspiration. The object consists of 50 mm cubes and in each row the cube touches the adjacent cube in its corner (intersection point) and they have one parallel continuous diagonal line for the whole row. The rest of the rows are the same but it is shifted half the diagonal length to one side to intersect the cubes corners with the previous row intersection points.

**Milling strategies** • 2 Axis engraving milling. • 12mm radius tool. • Maximum depth reached was 22mm. • Process took 40 min to finish. Presentation (PDF)
