Pseudonym of David Kümin, he was born in 1982 and grew up in Winterthur. Even as a child he was fascinated by murals and illegal graffiti. As a teenager he soon discovered the spray can and this encounter also marked his debut as an artist. He graduated from the Lucerne School of Art and Design in Fine Arts, specialising in Public Art and Art Teaching. His wall works, as well as his atelier works, are characterised by material and photorealistic painting, sometimes combined with typography and cartoons. His works always have a profound content and never a purely decorative character: the intention is to involve the viewer in an active confrontation with the work.
