"doesn't deform under stress... responses by structure rather than their chemistry... design frustration corresponds to non-orientable order affects response pushed or squeezed... rings of squares connected by hinges at corners, when rings squeezed, neighboring squares rotate in opposite directions... analogous to the anti-ferromagnetic ordering that occurs in certain magnetic materials... information storage, quantum computers, colloidal science, photonics, magnetism, robotics and atomic physics"
