Juno’s spinners are polyhedron models I discovered that links and transforms. With a simple operation, it expands and shrinks.

Juno’s spinner (the usual model of that) consists of two elements. A rotational joint connects the end of each element, and the whole model transform together by a motion being transmitted through the joint. Rotational movement of an element changes the distance of each element.
