Starting from a drawing, a pure creation of the mind, I expand it in space by giving it three dimensions, by giving it a material body [in polystyrene] and then enlarge it to the proportions of a site where it can evolve. In this way, instead of having only the drawing before you while remaining anchored in the everyday world, you can finally leave the world and penetrate into drawing, and thus inhabit the creation of the mind instead of merely looking at it prudently in a frame on the wall. The experience consists, therefore, in abstracting yourself totally from the natural everyday world in order to feed your eyes solely on your own mental elaborations.
