1. Rotating element sheet material comprising:

  • a substrate;

    enabling fluid; and

    a plurality of substantially cylindrical rotatable elements disposed in said substrate and in contact with said enabling fluid;

    wherein one of said plurality of rotatable elements comprises;

    a core configured to present a first aspect in a first orientation and a second aspect in a second orientation, where said first orientation and said second orientation are related by a rotational transformation about an axis of the core;

    wherein said rotatable element in contact with said enabling fluid is configured to exhibit a first addressable dipole that couples with a first vector field and a second addressable dipole that couples with a second vector field;

    wherein said rotatable element and said first addressable dipole are configured such that said rotatable element exhibits said first aspect in said first vector field oriented in a first direction substantially perpendicular to said axis; and

    wherein said rotatable element and said second addressable dipole are further configured such that said rotatable element exhibits said second aspect in said second vector field oriented in said first direction.
