The Liquid Check picnic plaid is a tribute by Federico Pazienza to Victor Vasarely , father of Op-art who in the 60s and 70s with his accurate style transformed into art the study of invisible architecture that is the basis of a perception of reality. Today, with the advent of digital, signs have definitively freed themselves from their meaning and Liquid Check allows Federico Pazienza to reflect on classic patterns, such as the tablecloth check, using digital to increase their visual strength, with intervention as simple as it is bold: like a stone falling into a pond, the digital transformation of Pazienza ripples a perfect matrix and the check of traditional tablecloths becomes fluid and pulsating pattern, a symbol of our liquid society.
