Tile mosaic, 800 x 100 cm
In the main restaurant at the back wall of the food serving area, a virtue has been made of necessity (to create a waterproof and steam-resistant wall covering) - using glazed, artistically arranged stoneware tiles. Instead of - as is often the case - swimming pool atmosphere, since 2001 there has been a tasteful homage to the Russian painter Wassily Kandinsky. Kandinsky had made a decisive contribution to the development of abstraction in the visual arts in the Occident as a separate free art form.

The "Sound of Spheres" at the academy was composed by Ferdinand Weißgerber. This picture is in dialogue with a mosaic picture that greets travellers in the staircase of Luxembourg City's main railway station (as of summer 2019). With this he underlines the connection to the Europäische Akademie Otzenhausen, which has always been committed to the growing together of the SaarLorLux Greater Region. Both mosaics were completed with the support of the company Villeroy & Boch, the one at the academy on the occasion of the reopening of House A (2001).
