Continuing to explore corrugations which are rigidly foldable – ie. there is no deformation of the faces during the folding process.
This has links to some surprisingly deep mathematics – in particular the subjects of discrete differential geometry and integrable structure – Which have important architectural applications (such as finding planar panelings of curved surfaces) and also tie in with my earlier interest in minimal surfaces and circle packings.


The same principles can be naturally extended to other piecewise-planar surfaces such as the one above, which is rigidly foldable but does not unfold to flat.
