1. A sprinkler nozzle, comprising:
a sprinkler axis;
a nozzle plate having at least one orifice formed therein; and
a stream deflector rotatably mounted adjacent the nozzle plate and having a plurality of flutes formed therein facing the nozzle plate, each flute having an inner portion that can momentarily align with a center of a first orifice in the nozzle plate during rotation of the stream deflector about the sprinkler axis relative to the nozzle plate so that water flowing through the first orifice will be channeled in a generally radial direction by the flute to form a stream of water that is ejected from the stream deflector, and further wherein a first flute extends in a first direction at a first angle in a plane perpendicular to the rotational axis of the stream deflector with respect to a line intersecting the sprinkler axis and the center of the first orifice when the inner portion of the first flute aligns with the center of the first orifice, wherein a second flute extends in a second direction at a second angle a plane perpendicular to the rotational axis of the stream deflector with respect to a line intersecting the sprinkler axis and the center of the first orifice when the inner portion of the second flute aligns with the center of the first orifice, wherein the plurality of flutes includes at least one flute other than the first and second flutes, wherein all of the plurality of flutes other than the first flute and the second flute extend in directions at angles between the first and second angles when the inner portion of each of the plurality of flutes aligns with the center of the first orifice, so that in combination the streams of water successively ejected from the stream deflector establish a predetermined shape of coverage entirely between the first direction and the second direction after the stream deflector rotates through an entire revolution, and wherein the first orifice in the nozzle plate is a single aperture offset from a center of the nozzle plate.
