Claim 1

A GEOMETRIC DEVICE COMPRISING: A PLURALITY OF RELATIVELY SHIFTABLE, POLYGONAL SECTIONS IN MODULAR ARRANGEMENT TO DEFINE A MODULE AND INCLUDING A CENTRAL SECTION AND A PLURALITY OF OUTER SECTIONS, SAID OUTE SECTIONS BEING DISPOSED IN CONTINUOUS CIRCUMSCRIBING, PROXIMAL RELATIONSHIP TO THE PERIMETER OF SAID CENTRAL SECTION, EACH OF SAID OUTER SECTIONS HAVING SIDE MARGINS THEREOF POSITIONED IN COEXTENSIVE, SUBSTANTIALLY ABUTTING RELATIONSHIP WITH THE SIDE MARGIN OF AN ADJACENT OUTER SECTION, A SIDE EDGE OF AN OUTER SECTION ADJACENT TO SAID CENTRAL SECTION BEING DISPOSED IN PROXIMAL COEXTENSIVE, SUBSTANTIALLY ABUTTING DISPOSITION WITH RESPECT TO AN ADJACENT SIDE OF SAID CENTRAL SECTION WHEN THE MODULE IS IN A CLOSED CONDITION; MEANS PIVOTALLY INTERCONNECTING EACH CORNER OF THE CENTRAL SECTION WITH THE PROXIMAL CORNER OF THE OUTER SECTION ADJACENT THERETO; AND MEANS PIVOTALLY CONNECTING A PAIR OF THE OTHER CORNERS OF EACH OUTER SECTION WITH THE PROXIMAL CORNERS OF THE OUTER SECTIONS ADJACENT THERETO TO PERMIT MOVEMENT OF ALL OF THE SECTIONS WHEN SAID CENTRAL SECTION IS ROTATED, A CORNER OF EACH SECTION BEING INTERCONNECTED WITH BUT A SINGLE CORNER OF ANOTHER SECTION OF THE MODULE.
