French artist, Eltono has been working in the public space for over fifteen years, notably through mural painting. He now plays with lines to repeat this adaptable form and make it a graphic motif constant enough to be identified but at the same time changeable enough to fit a given context. It is the way he articulates the lines and the colors he uses that allows him to adapt to the surfaces he paints on. During two weeks, the schoolchildren of La Grette and La Butte neighborhood, and a few lucky people had the opportunity to make a mural painting. A geometrical and random composition gradually took shape on the wall, which revealed new patterns everyday through the play of colours and assemblages.
