Building off the theme of a previous post, here is an example of a re-configurable formwork. All the panels are the same and all the panels are identical. By changing angles of the fold we are able to pleat or bunch, more and less locally across the surface. Here we are also able to simulate the range of movement as it's not infinitely flexible. As you pin the points, the overall assmebly begins to take its own form.
