GREGOS is a french street artist who started to display his face on the walls of Paris. He has developed his own 3D technique and is a self taught artist. He creates a molding of his face, tongue out or smiling, that he paints and glues on the walls of the globe. Each face is a self-portrait, showing the mood of the moment it was made. At first, the faces were only blanks, and the message was the tongue out. His street art concept is very successful as there is interaction between the faces and passers. As of today, more than 500 faces have been installed, mostly in Paris, but also in other towns of France and Europe, USA, Japan and South America.
