The installation was made on the walls of an abandoned house, one of many buildings in a similar condition in the Italian village Rosora (Province of Ancona). The project combined artistic and ecological ideas. The installation "Liquid Wall" refers to the transition of a material from a solid to a liquid state. The work itself, because of the use of transparent and glossy materials, changes depending on the position of the viewer, time of a day and weather conditions. The text in Italian and English consists of the international proverbs concerning rivers.
