Johannes Vogl's intervention was based upon an installation of light boxes that offer a temporary and spatially tranposed representation of natural subjects. Hereby, the pictures were no photographic or typographic reproductions but hand drawings created in the so-called scratch drawing technique. First of all, the surface of acrylic glass is completely blackened; later one scratches the color partially form the glass using scalpels and palette knives. Thus one creates a black-and-white drawing with strong contrasts.

For the installation "Fünf Monde" (Five Moons) four tower cranes nearby the parking area Heiligenstadt, Muthgasse in the 19th district in the northern parts of Vienna were used. Usually large advertising boxes showing the logos of the participating building enterprises are mounted at the level of the cranes' arms. Johannes Vogl replaced four of these light displays with drawings of a full moon. Viewers saw four fictive additional moons appearing on the horizon of the city beside the real one in the dark - hence the project's titel "Fünf Monde".
