Claim:
A six plate hollow parallelepipedal structure comprised of: three oblong rectangular first plates each having a first rectangular top surface and a first rectangular bottom surface and having a dimension of length and a dimension of width; and three oblong rectangular second plates each having a second rectangular top surface and a second rectangular bottom surface and having a dimension of length and a dimension of width; wherein said first rectangular top surface further comprises a bar traversing the length of said first top surface centered along a longitudinal axis of said first top surface and said second rectangular top surface further comprises two substantially similar linear members traversing the length of said second top surface and residing parallel to but offset from a longitudinal axis of said top surface such that a trough is formed there between said linear members, and wherein when said first rectangular plates and second rectangular plates are assembled into said parallelepipedal structure, said longitudinal axis of each said first and second rectangular plates resides perpendicular to said longitudinal axes of all rectangular first and second plates with which it shares a single common edge; wherein said trough is dimensioned to matingly engage said bar so as to allow sliding engagement with one another, such that when a multitude of parallelepipedal structures are assembled into an array, the individual structures are free to move about each other individually or in groupings such that there can be slab movement, row movement, or solo cube movement in an X axis, a Y axis and a Z axis by the complementary engagement of said trough and bar; and wherein said first and second bottom surfaces have two length edges and two width edges and further comprise a first and a second substantially similar linear members extending normally from said first bottom surface and said second bottom surface wherein said first linear member resides adjacent to a length edge and said second linear member resides parallel to said first member such that the said first and second bottom surfaces of said first and second plates are mechanically directly engageable to enable three first plates and three second plates to form a parallelepipedal structure.
