Truly flexible polyhedra are exceptionally rare. As far as I know there are no known flexible polyhedra using only regular polygons. This video is about one candidate that I found.

This is fascinating! I'd never come across the idea of flexible / non-flexible polyhedra before. And nice to see the huge pile of 2x2x2x2s!
