I have a cheap oscillating sprinkler that I sometimes use to water my lawn or garden. As it rotates back and forth, it lays down water in a striped pattern. Wet-dry-wet-dry-etc. If I want complete coverage, I have to go out and move the sprinkler a few inches, then move it again. What a hassle. Are there any oscillating sprinklers that wiggle or somehow randomize the spray pattern, so that it evenly covers the area being watered? I've googled "random oscillating sprinkler" and "wiggling oscillating sprinkler" with no success. I'm sure I saw something like this years ago, but I can't find it now.
