Abstract: The invention comprises a puzzle including elements arranged in rows and columns, each element being rotatable about first and second perpendicular axes. The first axis of each element is parallel and co-planar to the first axes of every other element. Similarly, the second axis of each element is parallel and co-planar to the second axes of every other element. The puzzle also preferably includes a case that restrains non-rotational movement of each element and a linkage that forces rotation of all other elements in any one row to rotate about their respective first axes when any one of the elements in that row is rotated about its first axis. The linkage also forces rotation of all elements a column to rotate about their respective second axes when any one of the elements in that column is rotated about its second axis.

Abstract: A housing assembly for a communication device including front and rear housings and an endoskeleton adapted to be secured to the front housing via recesses locate on the endoskeleton and corresponding ribs located on the front housing. The front and rear housings include a cantilever arm and loop assembly to secure the top ends of the front and rear housings to each other. The rear housing includes a pair of hooks located at its bottom end and the second housing includes a pair of latches located at its bottom end. The hooks each have a contact surface adapted to mate with a corresponding contact surface on each latch. The contact surface on each hook are outwardly sloped and the contact surface on each latch is inwardly and downwardly sloped. The contact surface slopes cause the hooks to deflect inwardly when the latches are snapped into the hooks.
