A floor in the Certosa of Calci
The floors at the Certosa di Calci (a monastery near Pisa) often have a 3D effect. The picture shows a wooden panel, created at the Istituto d'Arte "Russoli" in Pisa for the exhibition "La matematica sotto i piedi", which reproduces one of these floors. You can get a 3D effect in two different ways (concave or convex) - in this photo it is easier to see the convex effect, and you just need to turn it upside down to get the other effect. The type of symmetry of a pattern is different depending on whether you consider the color (o) or just the geometry of the figure (3*3).
This image has been used in the number 2 of the exhibition XlaTangente.
