The Miura map fold (aka Miura-ori) is an example of a rigid origami model (can be folded from sheet metal with hinges instead of crease lines) which has applications in solar panel design for space satellites. This Demonstration offers a proof, of sorts, that the Miura map fold is rigid when made from a tiling of any nonsquare parallelogram.
