Filling stitch for colorwork knitting

This is from the book mentioned earlier:

It's the diagram for a satin weave, but it would make a good pattern for a Fair-Isle-technique sweater's "lice stitch." The pattern does have symmetry, but it's confusing enough to the eye to look somewhat random. Also, since long floats in weaving are as undesirable there as they are in knitting, the maximum space between black squares is 5 white squares, which works well for Fair Isle.
