During Expo 2015 in Milan it was also presented an application that I developed with CRS4 (Samuel Iacolina, Pietro Zanarini, Carlino Casari). CRS4 finally makes interactive my digital typographic rugs, as I had imagined when I designed them. This app, named Sardinia Typestry (you can try it here) has become the digital gadget for Sardinia. It proposes, with a simple touch, an infinite combination of colours, randomly alternating upper and lower case of Battoro and PB1. Everyone can enter his name and the application returns infinite tapestries, vertically readable. Here are shown some combinations made digiting my name on the app.
