A curling effect is provided via a system, which may be included in an article, via a plurality of links, including distal, proximal, and intermediary links, that each comprise: a base; first and second wings, connected to opposite sides of the base such that each of first and second through-holes are aligned at a first height; and a header, connected between the wings that defines a third through-hole at the first height and a fourth through-hole at a second height different from the first height that is configured to accept a stringer there-through so that a force applied on the stringer in a direction from the distal link towards the proximal link causes rotation of neighboring links relative to one another; the neighboring links being joined via a linking axel disposed on a shared axis through the first, second, and third through-holes of the neighboring links.
