Claim 19:
20. A method, comprising:
forming a plurality of blocks, each block of the plurality of blocks comprising:
a first block portion having a first upper surface, a second upper surface, and a lower surface opposite the first upper surface and the second upper surface;
a second block portion over the first block portion, the second block portion having a third upper surface opposite the lower surface;
a third block portion over the first block portion, the third block portion having a fourth upper surface opposite the lower surface;
a fourth block portion over the first block portion, the fourth block portion having a fifth upper surface opposite the lower surface, the fourth block portion being positioned between the second block portion and the third block portion;
a first recessed region between the second block portion and the fourth block portion; and
a second recessed region between the third block portion and the fourth block portion,
wherein
at least one of the first upper surface is askew with respect to the lower surface or the second upper surface is askew with respect to the lower surface,
the first upper surface is exposed in the first recessed region and the second upper surface is exposed in the second recessed region,
a first through-hole extends through at least one of the first block portion or the second block portion in a direction transverse to a length direction of the first block portion, and
a second through-hole extends through at least one of first block portion or the third block portion in the direction transverse to the length direction of the first block portion;

arranging the blocks of the plurality of blocks in columns and rows such that:
the blocks of the plurality of blocks included in an ith column are aligned with the first through-holes and the second through-holes of each block in the ith column being aligned in an ith column direction;
the blocks of the plurality of blocks included in an i+1th column are aligned with the first through-holes and the second through-holes of each block in the i+1th column being aligned in an i+1th column direction; and
the blocks of the plurality of blocks included in the ith column and the blocks of the plurality of blocks included in the i+1th column are alternately arranged with the second through-holes of the blocks of the plurality of blocks included in the ith column being axially aligned with the first through-holes of the blocks of the plurality of blocks included in the i+1th column; and

coupling the blocks in adjacent columns, forming a mesh of blocks, using couplings that extend through the axially aligned first through-holes and second through-holes of the blocks of the plurality of blocks included in the adjacent columns.
