Patent ID: 6897848

Claim:
A kit comprising: rotating element sheet material; and a gradient field stylus; where the rotating element sheet material comprises: a plurality of rotatable elements disposed in a substrate and in contact with an enabling fluid; where the substrate comprises a plurality of sheet latching components; where at least one of the plurality of rotatable elements comprises: (i) a core configured to present a first aspect in a first orientation and a second aspect in a second orientation; and (ii) at least a first rotatable latching component and a second rotatable latching component; where the first orientation and the second orientation are related by a rotational transformation about an axis of the rotatable element; and where at least one of the plurality of sheet latching components is proximal to the first rotatable latching component in the first orientation; where the sheet latching component is proximal to the second rotatable latching component in the second orientation; where the rotatable latching components and the sheet latching component are configured to exhibit an attractive force when proximal based on a first gradient field; and where a distal end of the gradient field stylus is configured to exhibit an attractive force with the rotatable latching components when proximal based on a second gradient field.
