This challenging puzzle designed by Siebenstein-Spiele founder Jürgen Reiche requires a bit of thinking just to wrap one's head around how it works. The individual pieces consist of two layers, which can counter-rotate by means of a stainless-steel hinge. Thus, each piece can actually change shape. In order to solve the puzzle, both layers must be arranged into the 5x6 rectangle shown.
