The work was created in collaboration with Ludmila, the Ukrainian woman who cleans at the Program Galley. Uv-ink was added to her cleaning liquid which made her work visual under the uv-lights, which were set in space. The normal lights switched on when the uv-lights turned on as they were connected to timer. She didn’t want her photograph to be archived in internet, since her husband does not know that she is working in Berlin as a cleaner, and believes she works as a nurse. ..More about the work.
