The video presents, through sequentially presented photographs, the construction of the collaborative STEAM art installation titled Wall Drawing 2022.Lisbon.

It is a work carried out on the walls of the Maker Gunea de Basurto of the Bilbao City Council. The work is made with three-color acrylic paint and represents a sunset with the sea horizon seen through a lauburu-shaped window with horizontal and vertical rectangles.

The video shows the walls before the performance, and the progressive construction of the work by the voluntary participants (students from the Basurto school and the Faculty of Education of Bilbao and teachers from the UPV/EHU) who paint over the marks following the colors of the design made.

Background music gives continuity to the development of the work until the end of the work in which the final result is shown from different perspectives.
