Diogo Machado, alias Add Fuel, is a graphic designer and an accomplished Portuguese illustrator. He has recently redirected his attention to reinterpret the language of traditional tile design, and the Portuguese azulejo in particular. His interventions take place in the streets of the whole world : by using stencils and of aerosol bombs, he created complex and colored artworks, so precise that we could confuse with real tiling. For his series Street Ceramics, the artist uses real azulejo, replaced in situ.
