The artwork presented in March of 2011 at the summit of San Cristóbal hill, proposes a graphic intervention, a revisiting of the architecture, and a emplacement of a room in regard to the orientation of the sun. This triggers two sides of perception and analysis. On one hand, the work within its individuality and manufacturing methods, and how these can relate during the passage of a day, specifically with the solar motion. And on the other hand, the consequences of those events, such as the images projected through several beams of light on the floor of the Hall. The interaction with the spectator during the different times of the day conditions the experience of these drawings made out of cuts. Which makes this artwork a specific time and place of action.
