Sophie Petitpas decided to make Miami her home. And it was therefore in Miami that the French artist followed the attacks of 11 September live on CNN. This shock led to the idea of an artistic approach: using the American flag as a recurring motif for chromatic variations as a tribute to America. Who can forget those thousands of starspangled banners that citizens waved spontaneously in the wind in all the towns of the United States? More than the boundless barbarity of a terrorist act, it was the reflection of solidarity that aroused the enthusiasm of the artist.
