The wall art piece works with the shape of a 14th-century city wall built along the moat that originally ran down Na Příkopě street. This shape is divided into four glass segments, which are partly repeated on wooden frames, inspired by the shape of shop windows. While the glass shapes gradually decrease in number, leading to a single shape that incorporates the position of the 100Yards building, the frames are forming to the complete and clear shape. by the move outside the building, the entire process repeats in the opposite way and decrease into an abstract form.
