Città della terra cruda is a cultural association in which several municipalities of Sardinian hinterland (Italy) study and enhance the know-how of traditional ecological construction techniques in Sardinia. The association pays particular attention to the architecture and settlements in raw earth, considered as components of the landscape contributing to characterize the Sardinian territory, and also promote its sustainable development. To celebrate the twenty years of the association, I used the game of Tangram to create a visual system composed of colors and geometric shapes very simple. After sampling the colors of the raw earth, I assigned each shape a color, then played with the composition of the working pages. In this way, I was able to get many illustrations and make the communication less static.
