REACT is a collaboration between the University of the West of England, Watershed Arts Trust, (and its subsidiary iShed), and the Universities of Bath, Bristol, Cardiff and Exeter. It reaches across two dynamic UK regions, and uniquely across three cultural areas and two languages and creative economies. Together we will generate a transformation in arts-driven economic and social impact by combining demand from the Creative Economy with Arts and Humanities research excellence. Through REACT we will pioneer a new model of dynamic creative interaction: Sandbox.
