Paintings by 12,000 children are incorporated in an impressive art installation forming part of the fourth edition of the ŻiguŻajg Arts Festival that began yesterday. Each painting was digitised, printed and integrated in the installation, by Austin Camilleri, and is mounted at Pjazza de Valette, Valletta. Running until Sunday, the festival will feature 28 productions, including 12 shows from seven countries. For more information go to www.ziguzajg.org or www.facebook.com/ziguzajg.
