have the same base shape different base shapes or a combination for example each block 110 130 may have four edges forming squares wherein the blocks 110 130 are configured to be positioned adjacent to each other in further implementations blocks 110 may be dissected divided etc into smaller parts forming the same geometrical shape as the original block for example blocks 110 may be cut in half or quarters to be formed of triangles blocks 110 may be configured to be removed from system 100 rotated and reinserted into system 100 which may form a dynamic passageway 100 based on the layout of channel 120 channel 120 may be formed within a block 110 between projections 122 124 extending across portions of block 110 projections 122 124 may extend upward away from a face surface of block to vertically offset an upper surface of projections 122 124 from an upper surface of channel 120 channel 120 may be positioned between the sidewalls associated with projections 122 124 furthermore based on the respective positioning of first block 110 and second block 130 passageway 105 may seamlessly extend across both blocks 110 130 via the channels 120 126 alternatively a projection 122 124 on second block 130 may end channel 120 fig2 depicts a perspective view of block 110 according to an embodiment elements depicted in fig2 may be described above for the sake of brevity a further description of these elements is omitted as depicted in fig2 block 110 may include base 210 projections 122 124 channel 120.
