How long after the mowing does it retain the striped effect? Seems to me that

Good point. It certainly couldn't last more than a day or 2,
considering the speed at which grass grows. Someone once mowed my lawn
diagonally (with respect to the border) and I thought it looked really
cool. That afternoon. The next day, it looked exactly the same as when
mowed back&forth, in diminishing squares, or as I have occasionally
done, in spirals.

A permanent stripey effect might be achieved by using different
varieties of grass, or selective fertilizing, which seems mean. :-)
