When he started painting on city walls, he needed to choose a "tag" and opted for Nemo – like the captain from 20,000 Leagues Under the Sea, the protagonist of one of Winsor McCay's earliest comics, and last but not least, the Latin word for "nobody," which makes his work even more mysterious. He added the Saxon genitive 's so his artistic name would mean "nobody's," thus completing the paradox inherent in his way of self-identification. He began writing his name on walls before abandoning traditional graffiti and calligraphic aspects to reproduce his drawings instead. He thus transitioned to using characters and illustrations to express himself and visually translate ideas he couldn't communicate with words. His artistic journey led him to develop a particular interest in colors and recycled paper, searching for ways to "paint" his drawings. Until then, he had only used spray paint and acrylics, but paper had something special – it was a living material. NemO's work divides into graphic, essential images that convey social messages through characters performing poetic and surreal actions, like those from an undefined fairy tale. Recently, he began combining his "paper technique" with drawings addressing social issues.
