Looks interesting. Would it be possible to put the joint on the sides rather than on the top? That might help hide it better as the top is generally more obvious than the sides. Better yet, would it be possible to make the top and sides be one piece and the bottom be the other piece? That way the joints would be along the bottom corner edges? Or, could each of the top, side, and bottom be separate pieces that snap together and somehow hide the joints at each of the 4 corner edges?
