Folding a rectangle 1

The rectangle is divided into 4 parts. Input: the pink part. The 4 parts are connecting together by revolute joints, axes of which are concurrent. In fact, it is a spherical 4-bar linkage. The mechanism has an unstable position when all parts are in a plane. The mechanism is inspired by paper folding art.
