L'esboç infinit (The Infinite Sketch) is a site-specific generative art piece, as it only works when projected onto the wall for which it was conceived. It is a wall where two layers of activity have been preserved in the building where it is located: remains of paint from a house, and later marks made in pencil by workers, on a wall that is very imperfect in terms of texture. In the work, a virtual drawing mixes with these imperfections, color changes, and pencil marks of the real wall, creating a game of confusion between what is part of one world and what is part of the other.
