Summary

 * Author: Ben.
 * All wording: original.
 * Layout of 8 x 16 grid (128 squares) suggests a 128-bit, or 16 (8-bit) byte, number, turned into a crossword grid. (For full symmetry, the grid should be repeated and rotated in a 2x2 pattern.) This demonstrates how information can be relayed on two levels at once.
