Moving Walls is simple and visionary. White write-on walls can be freely combined and arranged in circle segments or as a long straight surface. They were developed in order to make visible, in the form of writing or drawing, the exchange of discussions, problems and suggestions within a group of people working in collaboration. The walls influence the process and content of collaborative thinking and substantially improve the outcomes of such activities. The walls are in use at the World Economic Forum in Davos and among many renowned companies and organisations worldwide.
