On Saturday 19 January 2019, starting at noon, Lee Mingwei will complete an unfinished section of the sand painting, Visitors are invited to walk on the sand - both the artist and the audience become part of a simultaneous process of creation and destruction. At sunset, after the last Visitor has walked on the sand, Lee and three performers will sweep the painting and leave it in this condition until the conclusion of the exhibition.

Guernica in Sand is a large-scale installation by Lee Mingwei, which is inspired by Pablo Picasso's Guernica, a monumental work by Picasso that has become a universal symbol of anti-war and an embodiment of peace. Over a period of three weeks, Lee has recreated the painting in sand and will use it as the basis for an interactive performance, midway through the exhibition.
