White autonomous lines live in a large space on the ground. They react to the passers-by, incarnating their near past and future paths. Autonomous and interactive, they play with their movements, anticipating and adapting, confronting them with their own free will.

Les Lignes-mobiles (The mobile-lines) is an interactive installation designed to insert itself in the reality of a public place, and which stems from a simple concept: a videoprojector projects lines on the floor, both according to the passers-by and in an autonomous way, improvised by a computer. These lines concretize, in a signaletic way, links and directions for the passers-by themselves or between them.

The lines are white, minimal, fluid, semi-autonomous, and sensitive to the passers-by. They appear and disappear, cross in arabesques. They choose some passers-by and get attached to them until they leave the projection zone, following them or preceeding them in their movement. They tend to create links between them. Les Lignes-mobiles set up an interaction zone, an interference zone between passers-by chosen at random, or between a passer-by and the line that got attached to him.

Les Lignes-mobiles is an installation designed to be adapted to the dynamic of the installation place: wandering or not, fast or slow, crossing or path, etc.
