The present invention comprises two or more rotatable three-dimensional bodies and a linkage between the bodies. By means of the linkage, the rotation of a first body causes a second body to rotate. In at least one of the rotational positions of the two or more bodies, the shapes of the bodies are designed to create a shaped cavity between a first body and a second body. The shaped cavity may be a tunnel, or the shaped cavity may be a recess or niche. As the at least two bodies are rotated, the shaped cavity may appear or disappear or may change shape, position, or orientation as the bodies are rotated.
