The Dancing Ribbon is an attempt to investigate soft walls. A tensile structure of spandex and metal is inserted in the Great Hall, a graded II building, located next to St Barts hospital in London. Cancer patients are welcomed in this space to share their stories, get emotional support and listen to music. The fabric that is chosen for its acoustic properties becomes at moments a harp to play on. The space allows for therapeutical and emotional support through counselling and music therapy: walls could be soft and performing. The Dancing Ribbon is a proposal for a Maggies center for Cancer rehabilitation
