[jokhyrhg] A word is a path among cubes

A cube in a cubical honeycomb is adjacent to 26 others (allowing adjacency through faces, edges, or vertices).  Equivalently, a king in 3D chess has up to 26 moves.  Coincidentally, there are 26 letters of the alphabet, so any sequence of letters is a directed path through a cubical lattice.
