Portugal is promoting itself as Europe's ultimate surfing destination. "Surf is Art" is an advertising campaign that puts technology and street art in the heart of the waves. Four surfers (Tomás Valente, Afonso Antunes, Alex Botelho e José Ferreira), equipped with GPS sensors, catch several waves. Their rides become colored lines. And these lines are used by graffiti artist Miguel Caeiro, also known as RAM, to make a painting. "Could surfing be an art as well as a sport? In Portugal, the answer could be yes. We brought together surfers, an artist and cutting-edge technology and challenged them to create a picture inspired by perfect waves," explain FCB, the advertising agency responsible for the campaign.
