Wha-T

Wha-T is the working name of Yannick Martin, a trained architect based in Marseille. He moves between painting, installation, printmaking and murals, starting from the breaking down and rebuilding of volumes and abstract forms. His pared-back compositions of symbols and signs read like visual puzzles or invented alphabets. In Marseille he painted the murals on the cours Julien staircase, including "Greedy", and he is the author of "The Box", a book at the crossroads of graphic design and architecture. In July 2026 he painted live at Plein Champ, the urban art festival in the Gué-de-Maulny park, Le Mans.
