Mostafa created an interactive light sculpture and a multiple channel sound system emitting recordings, digital sound elements and ambient sound sounds pre-recorded by the artist. The work was created by Mostafa in 2010, in the basement of Mawlwian Museum Cairo, that has a long history related to the Sufi rituals. The layers of history of the building inspired the artworks. The latest version of this work is presented in Yogyakarta with various adjustments to the biennale exhibition space, which generates interesting encounter with the local context.
